Thanks, we'll work on it.

When definitions are done well (and defined terms are chosen well), they
actually make an agreement more readable. I've been nicknamed the
"definition killer" in Harmony, I've whacked and trimmed so many of
them, but I still think we have too many and the ones we have are too
complex. :)

Okay, let's flesh out that scenario. (With the usual disclaimer that I
don't work for Canonical's legal department, and don't represent
Canonical in Harmony, so this is personal perspective.)

Let's say Canonical adopts a Harmony contributor agreement, either
copyright license or copyright assignment, and chooses Option Five. They
accept contributions to Upstart under the Harmony agreement, and release
Upstart under GPLv2. They go on doing this for a long time, and a
sizable body of code is collected from a wide variety of contributors
(it's a thriving success). Either the contributors own the code and
Canonical has a broadly open license to it (license), or Canonical owns
the code and the contributors have a broadly open license to it
(assignment).

Evil Company takes control of Canonical, and sets on a path that's
harmful to Upstart. There are any number of ways Evil Company could do
this, from pursuing development the existing contributors consider a bad
technical direction for the project, to embarking on business models the
existing contributors find morally objectionable, to entirely refusing
to update or distribute Upstart. (See Mambo and Joomla! for an example.)

What can the contributors do? The first bit: Under either license or
assignment, the contributors have the right to take their contributions
and establish a new project (call it Startup) under any license they
choose. If the contributors are unified in this action, they're going to
carry a large body of the code away, possibly even all of it. If the
contributors disagree on whether to leave the old project, then Startup
will have control over a smaller body of code. I find it appealing that
each contributor casts their vote on what to do, using the code that
they wrote. That code is their stake in the project.

The second bit: For the rest of the code in Upstart, the parts that
weren't developed by the contributors forming Startup, they still have
the full body of Upstart code from the most recent release (version
42.0) under GPLv2. Evil Company can't take that back. Once 42.0 is
released as GPLv2, it's always available as GPLv2. And, what's more,
because of Option Five's reciprocity, the Startup developers have access
to the full body of any contributions checked into Upstart after release
42.0, also under GPLv2.

The third bit: Evil Company can't escape the reciprocity, because the
Harmony agreements guarantee (section 6.2) that Canonical can't give
Evil Company the rights they got from the Harmony agreements unless Evil
Company agrees in writing to respect all the terms of the Harmony agreement.

No one acquires a patent through contributions, all they acquire is a
license to a patent.

The fundamental problem is that software patents are a really, really,
really bad idea. When Harmony and other FLOSS contributor agreements and
licenses handle patents, we're not fooling ourselves into thinking that
we can fix software patents this way. All we're doing is partially
defusing the bomb, creating an ecosystem where, as much as possible,
contributors, projects, and users can work without fear of software patents.

99.99...% of contributors to FLOSS projects don't own patents, so the
patent license doesn't apply to them. For the small fraction of
contributors (mostly corporate) who do own patents, the "best practice"
that's grown in FLOSS is to take patent licenses from contributors for
anything infringed by their contributions. That's enough to protect the
project (and the users) from evil companies slipping in code covered by
their own patents, then turning around and attacking the project, or
more likely attacking some big, wealthy company that uses the project.

Curiously, this kind of defusing behavior is exactly how patents are
mostly used in the rest of the world. "I'll license you my patents if
you license me your patents, and then we'll both be accountable to the
other and won't be able to attack." It isn't perfect, but it's the best
approach so far to a broken system.



In the specific case of Upstart and Canonical, you have one advantage in
the fact that Canonical is completely against software patents, as
evidenced by their lobbying to the European Patent Office, and in
multiple public statements by the founder (e.g.
http://www.markshuttleworth.com/archives/118).

In the case of an Evil Company patent troll, who holds a number of
patents relevant to Upstart, the first question is "How did they get
those patents?" If the Upstart code existed before the patent, that's
prior art, and the patent can be invalidated.

If the patent existed before Upstart, then you're in trouble. Evil
Company may have nothing to do with Canonical, and you're still in
trouble if they decide to make a mess of things. Just rip that code out
of Upstart (or the fork Startup), it's far less painful than the
alternative. Patents are by nature narrowly defined, so you're looking
at rewriting one algorithm, process, or feature to avoid the patent, not
losing the entire codebase.

Oddly, you're slightly better off on this point if Evil Company does buy
Canonical, because then any patents Evil Company holds that are
infringed by Upstart, are covered by the Harmony patent license. Evil
Company's patent claims against Upstart are weakened or destroyed once
they're a party to the Harmony agreement (that's one of the relevant
purposes of the patent license).

Sounds like a reasonable idea. One advantage of GPLv3 is clearer patent
protection than GPLv2. The FSF, SFLC, and RMS took the position during
the GPLv3 process that GPLv2 had an implicit patent license (search for
"implicit patent license" in http://gplv3.fsf.org/rms-why.html), you can
decide for yourself whether you agree with that. Apache 2.0 is another
option with clear patent protection.
