## Cryptographic Autonomy License {#cal}

[Van Lindberg][vanl_cfc]
requests comments on his Cryptographic Autonomy License (CAL),
a network copyleft license motivated by blockchain-based software.
He also wrote a [blog post][vanl_blog]
explaining the license’s background and rationale in detail.

### User Data and the GDPR {#cal-gdpr}

The CAL has provisions that ensure user’s access to their data,
which goes in a similar direction as the EU’s GDPR
– it even references the GDPR in an interpretation clause.
The CAL defines a concept of Lawful Interest
as the trigger for user access rights.

[Henrik Ingo][ingo] notes that
this grants rights to third parties,
which is fairly novel and could raise OSD issues.
[Van Lindberg][vanl_ingo] says
these are just third party beneficiaries
that receive no rights other than
access to the Source and to their own User Data.
The data protection in the CAL is not a grant of rights to third parties,
but a limitation on the grant to the licensee,
similar to the GPLv3’s anti-Tivoization clause.

Henrik Ingo [[1][ingo],[2][ingo_gdpr]]
dives a bit deeper into the CAL ↔ GDPR relationship,
and finds CAL User Data to be inconsistent the GDPR personal data concept.

[Van Lindberg][vanl_ingo] responds that
the CAL and GDPR have different angles:
GDPR is primarily concerned about privacy,
the CAL primarily about User Autonomy.
Lawful Interest is intended to
not only capture rights through ownership or the GDPR,
but also things like the right to an ebook the user possesses or has licensed.
The CAL’s User Data concept is more broad than the GDPR’s Personal Data.
Based on Ingo’s feedback,
[Lindberg][vanl_gdpr] updates the wording of the CAL
to clarify its relationship with the GDPR.

### Public Performance {#cal-public-performance}

The CAL triggers some license obligations on “Public Performance”,
an aspect of copyright not explicitly discussed by existing Open Source licenses.
This is intended to create a network-copyleft license like the AGPL,
while being less specific to a medium or technology.

Henrik Ingo [[1][ingo],[2][ingo_gdpr]] is a bit put off by this unusual term,
similar to the usage of Conveyance in the GPLv3.
The CAL also doesn’t make it clear
what “Publicly Performing an interface” means.
Is there any precedent for applying public performance to software?
What is an interface?
How would this apply to a library API?
Ingo is also concerned that public performance could be too broad
so that it would cover way more than SaaS style use.

[Van Lindberg][vanl_ingo] points out that
Public Performance is a well-established term in copyright law,
but [concedes][vanl_gdpr] that its application to software
is less well defined.
Lindberg intends “interface” to be interpreted broadly, from GUIs to APIs
– as long as it can be protected by IP law.
This should definitely cover more than just SaaS use.
After all, the CAL tries to ensure
user autonomy in distributed software systems.

[Henrik Ingo][ingo_undefined] thinks
the lack of clarity around public performance
is a major weakness of the CAL
– maybe specific uses should be always allowed,
similar to how the GPL gives unlimited permission
to run the unmodified program?

[ingo_undefined]: http://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-March/020368.html

Bruce Perens [[1][perens_oppress],[2][perens_literary]]
isn’t sure whether the U.S. copyright law
provides a sufficient public performance rights for the CAL to work,
in particular whether software is a literary work.
[Van Lindberg][lindberg_copyright]
provides numerous references for both US and international law
that software is treated as a literary work.
(Note: see also the WIPO Copyright Treaty.)
It follows that literary works’ performance rights must also apply to software.

### Other Notes {#cal-other}

[Henrik Ingo][ingo]:
isn’t “Compatible Open Source License” just any OSI-approved license?
Van Lindberg [[1][vanl_ingo],[2][vanl_gdpr]] responds that
the CAL defines Open Source licenses as both OSI- and FSF-approved,
but that compatibility is determined by the terms of the other license.

The CAL allows a simple LGPL-like exception to be added.
[Henrik Ingo][ingo] would prefer if that was
a clearly separate license with its own name.
[Van Lindberg][vanl_ingo] doesn’t think this would be a problem,
just as there isn’t a problem with different GPL exceptions like Classpath.

The CAL significantly expands the reach of copyleft licensing,
in particular to public performance.
[Henrik Ingo][ingo_undefined] thinks
this “copyright maximalist” attitude is regrettable,
and echoes [Bruce Peren’s][perens_jan_extension] opinion that
“Extension of copyright is bad for open source”.
[Van Lindberg][vanl_maximalist] responds that
the CAL tries very hard to fit within the established reach of IP law.

[perens_jan_extension]: https://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-January/020261.html
[vanl_maximalist]: http://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-March/020376.html

[Bruce Perens][perens_oppress] thinks that
restricting the license grant to copyright and patents
may be too narrow for jurisdictions that recognize additional rights.
Perens suggests the license should grant all necessary rights,
and only exclude trademarks.
[Van Lindberg][lindberg_copyright] considers broadening the grant.

Bruce Perens [[1][perens_oppress],[2][perens_osd6]]
thinks that the CAL’s anti-DRM clause is too narrow
as it focuses on specific techniques like cryptographic keys.
This could even be understood as a OSD #6 usage restriction.
Van Lindberg [[1][lindberg_copyright],[2][vanl_osd6]]
agrees that could be too narrow by itself,
but that the license also contains more general anti-DRM clauses.
The mention of specific technologies was requested by his client.
This isn’t so much a user-restrictiction as a kind of anti-Tivoization clause
made necessary by the environment for which the license is being developed.

## Discussion of License-Review process {#process}

In the context of the SSPL’s withdrawal from OSI review
(see the [License-Review] summary),
[Josh Berkus][berkus_disappointed]
voices disappointment with the License-Review process:
instead of legal discussions on the contents of the license,
Berkus saw ad-hominem attacks.

> [This] was a dramatic failure of the license-review process,
> and I think shows that this group needs to be reconstituted. […]
> We need a real process around license approval that isn’t
> “outlast the licensing wonks with the most free time.”

This sparks extensive discussion on
whether there was a problem,
how the SSPL review should have worked instead,
how reviews work,
what the problems with email lists are,
and whether there might be alternatives (Discourse?).

### Views on tone and conduct of the list {#process-conduct}

[McCoy Smith][smith_what]
and Richard Fontana [[1][fontana_puzzled],[2][fontana_branch]]
don’t share Berkus’ view.
Discussions about MongoDB’s business model aren’t ad-hominem attacks,
but closely related to the license’s practical effects.
Overall, it remained fairly civil.
Fontana saw “energetic and serious discussion […]
from an unusually wide variety of commenters”
and is concerned that curtailing “opinionated, impassioned” discussion
“could have the effect of stifling debate and expression.”

[Bruce Perens][perens_civil]
thinks that discussion remained civil,
but that he can’t respond to some people
without it being perceived as a “shouting match”.

[Josh Berkus][berkus_wtf]
reports that people on the “outside” are baffled and appalled
by conduct around the SSPL discussion.

> The OSI only has authority to the extent
> that we are widely regarded as an impartial arbiter
> of what is and is not open source.
> It’s important.
> And on the SSPL, we are *not* widely perceived as fair or impartial.

[Richard Fontana][fontana_lists] points out that
License-Review is a public list
and shouldn’t be conflated with the OSI.
And OSI didn’t get to be an arbiter on the SSPL
because the license was voluntarily withdrawn.
However:

> Participants on license-review are expected to adhere to the code of conduct,
> but they are not expected to be neutral or non-opinionated[.]

[Rick Moen][moen_discourse_review]
suspects that the discontent with the list’s discussion culture
is just “passive-aggressive kickback
against License Committee decisions they didn’t like”.
Richard Fontana [[1][fontana_suspicion],[2][fontana_lists]]
shares that suspicion: “this sounds to me like a complaint
that most of the active participants in the license-review threads on SSPL
were hostile to SSPL.”

[Perens][perens_civil]
thinks the problem is that discussion turned repetitious.
[Lawrence Rosen][rosen_repetitious]
responds with an 8-point manifesto with his most-repeated points.

Luis Villa [[1][villa_screaming],[2][villa_nope]]
complains about the volume and quality of discussion.
Debate is
“only valuable to the extent that they help [and]
the current quality and nature of the discussion don’t do that very well”:

> at some point I checked in […]
> to see that the thread was *literally 100 emails*,
> considered how negative (and often circular) the earlier parts had been,
> and said “nope, life is too short”.

### Should the SSPL review have had a different focus? {#process-sspl}

Where [Josh Berkus][berkus_wtf] would like to have seen
discussions about copyleft and the OSD in general,
[Richard Fontana][fontana_puzzled] reminds that the license review is not the place for that.
The review should only check whether the license
“conforms to the Open Source Definition and provides software freedom.”
But for Berkus these are not separable:
the question of OSD compliance
is directly related to
the question how far copyleft can and should be extended.

To Berkus’ dismay, the recent [CopyleftConf] didn’t see much discussion
specifically about the SSPL.
[McCoy Smith][smith_presentation]
summarizes some points from his talk at the conference
which did mention that license
and discusses a hypothetical Extreme Copyleft Public License as a though experiment.
Smith also points out that the AGPL addresses SaaS business models,
so it isn’t like the OSI had an anti-SaaS bias.
Smith doesn’t think the community would have a fundamental objection
against extending copyleft beyond AGPLv3.

### The list’s role in the license-review process {#process-list}

[Rick Moen][moen_discourse_review] proposes that
if the fundamental problem is that
License-Review discussions are mistaken for official OSI position,
that could be solved if people speaking officially self-identify themselves better.

[McCoy Smith][smith_process] sees the following criticisms being made here,
and discusses them in more detail:

1. a few loud voices have undue influence on review decisions
2. the voices lack variety, or do not reflect the “silent majority”
3. it is unclear how review decisions take the email discussions into account

[Bruce Perens][perens_vote] notes about the latter point
that the lists are merely advisory,
and that the decisions are made by the OSI board in a vote.
But there’s a lack of transparency in how the board reaches its decisions.
Do the board members even read the License-Review list?
And how did which director vote?
[Mike Milinkovich][milinkovich_vote]
shares his experience as a previous board member:
nearly all license approval votes were unanimous.
There is also more to the board than voting on licenses,
so not every board member should be expected to be a licensing expert.

Richard Fontana [[1][fontana_process],[2][fontana_lists]] adds that
most license submitters retract their license
if it’s not clear that it will be approved.
This month’s vote on the CFSL might have been the first rejection.
In that sense, the question isn’t whether loud voices
have undue influence on the OSI,
but what effect they have on the submitter.
MongoDB retracted the SSPL just a few days before the board vote,
citing a failure to reach a community consensus on the license
(which was more than just the license-review discussion).

[Ben Hilburn][hilburn_process]
thinks Fontana’s distinction
between influence on OSI vs influence on license submitters
is really important.
But while some disagreement is normal and expected,
it may also be important to protect the submitter and the debate
from negative conduct.
Hilburn cautions:

> *especially* for licenses where License-Review recommends rejection,
> our process and debates really needs to be trusted.

### Problems with email, and alternatives {#process-tools}

[Bruce Perens][perens_civil] mentioned discussion turned repetitious.
[Andrew DeMarsh][demarsh_repetitious] too
thinks the medium of mailing lists
makes it easy to discuss the same topics again and again,
without being able to easily reference their previous occurrence.
This is boring and tiring for list participants.
Maybe a better front-end to the mailing lists would help.

Luis Villa [[1][villa_screaming],[2][villa_nope]]
highlights that the current email-based review process
has a number of issues or limitations:

* limited visibility into the process from the outside
* too easy to generate vasts amounts of discussion
* these monthly summaries are too infrequent to guide discussion
* specific issues are not listed or tracked
* difficult for outsiders to join constructively,
not just with drive-by comments
* no way to silently signal agreement
* [McCoy Smith][smith_process] adds: archives are difficult to search

Villa suggests that the Discourse software might offer a better platform,
but really that any other tool than email would be an improvement.
Any tool will have *some* drawback,
but Villa believes
Discourse will reduce the barrier of entry to the discussions.

[villa_screaming]: http://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-March/020279.html
[smith_process]: http://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-March/020284.html

[Rick Moen][moen_discourse_review]
provides a critical summary of his experience with Discourse,
for example mentioning the lack of threaded discussion.
In contrast, [John Sullivan][sullivan_caretaker] notes
that the FSF is happily using Discourse.

[moen_discourse_review]: http://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-March/020293.html
[fontana_suspicion]: http://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-March/020308.html

[Richard Fontana][fontana_branch] thinks Discourse would be worth trying,
although it may be geared to different kinds of discussions.
Fontana doesn’t think that
“new tools will solve what are fundamentally social or political problems.”
[Villa][villa_nope] responds that tools do ease the symptoms.

Rick Moen and Thorsten Glaser
[[1][moen_contract],[2][moen_contract2],[3][glaser_contract]]
are concerned that using Discourse
would require discussion participants to enter a contract
with a third party hosting company.
[Kevin Fleming][fleming_contract] and [Michael Downey][downey_contract]
responds this wouldn’t be the case.

[Bruce Perens][perens_mail] suggests that at least,
the list archive software could be upgraded to something better than Pipermail,
which only supports plain text emails.

Responding to an offhand mention of Bugzilla or GitHub,
[Fontana][fontana_branch] argues that they
would be elitist and keep non-technical people out.
“several years ago I entertained the idea
that it would be obviously beneficial for license drafting
to adopt the preferred tools of developers. […]
I see now that […] involved a lot of romanticization
of developers and open source development.”

[Ben Hilburn][hilburn_email] agrees with some of the problems around email,
but appreciates that email lets the user choose their clients and workflows.
Some web-based tools can be integrated with an email-based workflow,
which may be desirable.

[hilburn_email]: http://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2019-March/020335.html

### Would a PEP-style process help? {#process-pep}

[John Sullivan][sullivan_caretaker]
suggests that the process could be improved without having to change the tools.
For example, each license application could be assigned a (volunteer) caretaker
who maintains a dossier with the salient points of the discussion.
In the end, any process will rely on individuals,
and no process will be able to prevent
louder voices or individuals with agendas.

[Chris Jerdonek][jerdonek_pep]
draws a comparison to Python’s PEP model
([Python Enhancement Proposal][pep])
where discussion is summarized in a central document.
Such a document would also be useful for further reference.
[Van Lindberg][vanl_pep] and [Ben Hilburn][hilburn_process] concur.

[Bruce Perens][perens_mail] and [Jerdonek][jerdonek_pep2]
caution that discussion in the PEP process
is still mailing-list based with all the drawbacks of the medium.
[John Sullivan][sullivan_pep] and [Jerdonek][jerdonek_pep2]
explain that having the central PEP document
helps to keep the discussion on track
and makes it easier to join the conversation later.

[Bruce Perens][perens_consensus]
is concerned that a PEP-like process
might have difficulty achieving consensus
for political decisions like license approval.
Perens points at the W3C, which used to make consensus decisions
until patent policy issues caused insurmountable disagreements.
[Chris Jerdonek][jerdonek_consensus]
sees PEP more as a documentation thing,
not as a consensus-building process.
Approval decisions are made externally
(Note: compare the role of the OSI board).

[Van Lindberg][vanl_pep] illustrates how the PEP process
relates to the review of his CAL license (see below).
Here, Lindberg tracks various arguments in a PEP-like blog post.

Who should maintain the PEP summary?
Pamela Chestek [[1][chestek_pep],[2][chestek_editor]]
suggests the license submitter could be be tasked with this
in order to avoid burdening volunteers.
[Luis Villa][villa_pep] thinks it might be hard for submitters
to determine the useful and important arguments
that should be covered in the summary.
Bruce Perens [[1][perens_pep],[2][perens_editor]]
thinks a process editor (or group of editors) can be useful.
That might be a job for legal professionals,
but not for volunteers on the list who might have a stake in the outcome.

Richard Fontana [[1][fontana_editor],[2][fontana_editor2]]
is concerned about possible bias in the summary,
both if it is maintained by volunteer editors
but especially if the license submitter were responsible.
Having a group of editors might help though.
[Perens][perens_editor2]
thinks submitter-written summaries could work
if the summary document has a clear version history,
and the submitter is paired with an unaffiliated editor.

Luis Villa [[1][villa_pep],[2][villa_editor]]
suggests more collaborative Wiki-ish approaches,
or that revisions of the summary
would have to be approved by an independent person.
[Villa][villa_editor2] is less concerned about bias,
more that a useful summary is written at all.

[Chris Jerdonek][jerdonek_editor]
explains that submitter-written summaries can work
if bad/biased summary will be cause for a license rejection.
Version control etc. is important, though.

## The pro-se license constructor {#pro-se}

The License-Review list saw a submission of a license
that didn’t have previous legal review.
That raises the question whether it is safe and acceptable for non-lawyers
to create and submit licenses.

Bruce Perens [[1][perens_crayon],[2][perens_crayon2]] argues that
it is dangerous to promote “Crayon Licenses”.
Without legal review, the actual effects of that licenses are unknown.
“I thus feel all such things should be rejected,
although the reason is entirely outside of the OSD.”

As an example, Perens [points to][perens_artisic] the Jacobsen v Katzer case
about the Artistic License, which Larry Wall had drafted pro-se.
The case could have set
“an absolutely horrid precedent […]:
that the license was tantamount to a dedication to the public domain.”

[McCoy Smith][smith_barriers] warns that requiring prior legal review
would be a barrier to entry,
could cause the review discussion to be dominated by lawyers,
and wouldn’t guarantee license quality.
[Perens][perens_defender] suggests the barrier could be avoided
if the OSI would assign a lawyer like a “public defender”.
[Henrik Ingo][ingo_cost] doesn’t see an issue with a barrier to entry:
There are plenty of approved licenses already available.
And the license-review process isn’t zero-cost either,
the cost is just born by OSI. (Note: and the community!)

[Brendan Hickey][hickey_barriers]
digs into the purpose of barriers and legal review.
Hickey doesn’t think that legal review
would be suitable to protect end users of the license.
And legal probably shouldn’t be the first step:
“No one should be hiring an attorney
to draft a license that will be rejected out of hand.”

Nigel Tzeng [[1][tzeng_nosa],[2][tzeng_nosa2]]
claims that advice from lawyers would be ignored anyway,
which seems to reference the NOSA review.
[John Cowan][cowan_nosa] points out that a license may be a fine legal document
but still fail to conform to the OSD.
[Tzeng][tzeng_nosa2] and Bruce Perens [[1][perens_nosa],[2][perens_nosa2]]
rehash some of the discussion around the NOSA.
After a while that argument flows into the more general discussion
about the license-review process, covered above.

[Van Lindberg][vanl_review]
discusses different aspects of license review.
On one hand there are policy choices and community considerations,
but determining whether a license is legally sound and complies with the OSD
is “strongly legally inflected”.
[Richard Fontana][fontana_lawyering] takes issue with that:
The OSD is not a legal document but
“a statement of philosophy and policy aimed at nonlawyers.”
Determining OSD compliance might require lawyer-style thinking,
but “a nonlawyer who is steeped in free/open source legal policy […]
might be much better qualified to interpret the OSD”.
Lawyers might also be biased, for example when they are representing a client.
While input on the legal soundness of a license
is valuable and requires legal specialists,
e.g. in case of the SSPL the policy arguments were ultimately more important.

## Leftovers {#leftovers}

[Thorsten Glaser][glaser_motif]
cross-posts a discussion from the Fedora-Legal list
about whether the Open Motif license can be considered open source.
Open Motif has an unusual license
that restricts its use to “open source” operating systems.
[Bruce Perens][perens_motif] considers this OSD #9 and #10 violations.
[Florian Weimer][weimer_motif]
points out that RHEL nevertheless ships Open Motif,
and he doesn’t think this restriction would be problematic.

The GPLv3 allows additional terms
that prohibit misrepresentation or decline trademarks.
[Patrick Schleizer][schleizer_gpl_misrepresentation] asks:
Does that mean the GPL grants such rights by default?
[John Cowan][cowan_gpl_misrepresentation]
argues that failure to prohibit something is not permission.
Similarly, [Bruce Perens][perens_gpl_misrepresentation]
points out the lack of affirmative statements that would grant these rights.
And the licenses don’t have to cover everything in detail:
they are embedded in a wider legal context.

End users of open source licenses
typically don’t explicitly accept the license.
Patrick Schleizer [[1][schleizer_clickwrap],[2][schleizer_gpl_disclaimer]] asks:
Doesn’t that mean any limitations of liability are ineffective
because the end user never *waived* their rights?
Or can warranties be unilaterally *disclaimed* by the author?
Does this differ between common law and civil law jurisdictions?
[Thorsten Glaser][glaser_clickwrap]
suggests that disclaimers are a condition on the copyright license.
[Van Lindberg][vanl_gpl_disclaimer]
points to the difference between licenses and contracts
(Note: which may be an US-centric viewpoint).

[Chris Lamb][lamb_parallel]
links to the [discussion on the Debian bug tracker][debian_parallel]
about the “citationware” requirement of Ole Tange’s GNU Parallel utility:
the utility prints out a demand to cite the software
or to pay the author a lump sum.
[Jonathon][jonathon_parallel] contrasts academic conventions around citation
with the wording of that requirement.
[Bruce Perens][perens_parallel] notes that in the meanwhile,
the citation requirement has been reduced to a non-compulsory request.

Responding to [January’s discussion][License-Discuss-2019-01]
about “intimacy”, [Florian Weimer][weimer_intimacy] adds
that AGPL compliance is particularly unproblematic
for quine-like programs that can provide their own source code.
