Updating Genode's license to AGPLv3 + open-source linking clause

the discussion has largely deviated from the original topic, which is
Genode's move from GPLv2 to AGPLv3. Please note that the relationship of
proprietary software and Genode remains untouched by Genode's license
Even though I am little afraid of the discussion getting further
derailed, I don't want to leave your remarks unanswered.

You are mixing up cause and effect. As I noted in my previous posting,
proprietary application vendors target their applications at consumer
platforms, they don't create consumer platforms.
Since Genode is not a consumer platform, it is uninteresting for
proprietary application vendors. The same is evident in the GNU/Linux
world. In contrast to, let's say Android, iOS, or Windows, GNU/Linux is
_not_ a consumer platform. So Adobe does not make Photoshop available on
Consumer platforms are generally not created by grassroots movements.
They don't happen to exist by chance, but they are planned products and
marketed as such. Unless a platform vendor pursues the creation of a new
consumer platform based in Genode as a product, the discussion about
accommodating proprietary software with the open-source Genode system
remains moot. It does not solve any problem.

This would be both impossible and wrong.
It would be impossible because there is no reasonable distinction
between kernel-level components and other components on Genode. Given
Genode's flexible architecture, even the attempt to draw a line would be
futile. Capturing this attempt in the form of legal terms would result
in a convoluted license full of heuristics (and thereby loopholes).
But even if it was possible, it would contradict with the position I
* It would dramatically weaken the effectiveness of our copyleft
license because - in principle - *any* functionality could be
implemented in the form of proprietary code that solely uses the
* It would benefit no one other than proprietary application vendors.
Making such a concession would help them, but neither Genode nor
the Free-Software community at large.
* It would undermine the dual-licensing business model of Genode
Labs and thereby the funding source of Genode's development.
Still, the world is not black and white. There are certainly cases where
proprietary software on top of Genode makes sense. Let me give you two
A consumer platform vendor wants to create a platform based on the
open-source Genode system. That is, the base system is AGPLv3 and all
drivers and the software stack are open. Still the vendor wants to
create a distribution channel for proprietary applications (an app
store) or other digital goods (games, movies). In this case, the vendor
could seek an exemption from the AGPLv3 for its app-store application in
exchange for letting Genode Labs participate in the commercial success
of the consumer platform. Under this model, Genode would indirectly
benefit from the proprietary application vendors. So an exemption is
granted for a tangible benefit for Genode.
As another example, for some software the source code may got lost. So
it becomes technically impossible to comply with the AGPLv3. The ability
to combine such software (e.g., "abandonware") with Genode should not
pose a problem.
That said, both stories are very different. I think it is impossible to
cover such a variety of corner cases in generically applicable legal
terms like our linking-exception clause. They should instead be
considered on a case-by-case basis. If confronted with such cases, I see
it as the responsibility of Genode Labs to take even-handed decisions.
Frankly speaking - looking at the past 8 years - I don't foresee that
happening too much.
