[License-review] For Approval: License Zero Reciprocal Public License

A quick bit of procedural history:  My
original message to license-review didn't get
delivered, for whatever reason.  A follow-up did.
This reply reproduces my initial responses to the
new-license questionnaire, along with with the
most recent text of the proposed license.

Submission:

I am submitting the License Zero Reciprocal Public
License (L0-R) for approval as an Open Source
license on behalf of Artless Devices LLC.  Artless
Devices LLC is a California business entity, and I
am its sole member and manager. The company
operates licensezero.com, a software
dual-licensing and relicensing agency.


Rationale:

L0-R aims to implement a clear and
stronger-than-strong variant of copyleft,
minimizing community-side legal pondering and
maximizing dual-licensing opportunity.


Distinguish:

1. L0-R is based on BSD-2-Clause.  L0-R adds
   metadata to the copyright notice, a notice of
   source code availability, obligations to retain
   the new notice, and a new, third, copyleft
   condition.

2. L0-R sits with the stronger copyleft licenses,
   such as GPL and AGPL.  L0-R's trigger for
   copyleft breaks sooner, on "execution" or
   "development" of software with the licensed work,
   rather than distribution or provision over a
   network.  L0-R's copyleft obligations are both
   stronger and weaker.  Subject software must be
   published as source code, but can be licensed
   under any combination of OSI-approved terms.

3. L0-R stands distinct from all Open Source
   licenses of which I'm aware in three lesser
   respects.  First, it directs licensees to an
   agent for sale of alternative licenses.
   Second, it sets up automatic waiver of its
   copyleft condition in the event alternative
   licenses cease to be available.  Third,
   copyleft obligations kick in only after a
   grace period of some calendar days.

3. L0-R grew out of a prior license, the License
   Zero Noncommercial Public License (L0-NC), also
   based on BSD-2-Clause:

   https://licensezero.com/licenses/noncommercial/diff

   L0-NC is clearly _not_ Open Source, though it
   reverts more directly back to an unmodified
   BSD-2-Clause by effect of its automatic waiver.


Legal Review:

I am a licensing lawyer, I took the first drafts,
and I made the first revisions.  I've been
fortunate to receive very generous private
feedback from fellow attorneys, but I will stand
behind this proposal alone.


Proliferation Category:

Other (with a follow-on question)

L0-R is not yet in wide current use, evidencing a well
known chicken-and-egg problem ... and a nice
structural brake on needless proliferation.  I
believe L0-R does enough that's new and useful to
warrant review.  I believe it would proliferate
new ideas.

I would also be interested in the correct process
for, and results of, reviewing L0-R terms assuming
automatic waiver of condition 3, by its own terms.
I suspect those terms would be classed "Redundant",
especially of BSD-2-Clause, despite the added
source-availability notice.


Plain Text:

The plain text of the license follows.  This text
is _not_ final, and I look forward to feedback.
Text set <like this> denotes a placeholder.  I'm
by no means wedded to that convention.
