Ecco, come immaginavo, una sana ed equilibrata risposta di FSF alle
"corbellerie" :) dei kernelisti.

With amazing timing...there has just been a release from the GPLv3
process that directly addresses some of the developer concerns about the
license. I have posted it pretty much in full below because it's
exactly what we're talking about.
The Free Software Foundation wishes to clarify a few factual points
about the Second Discussion Draft of GNU GPL version 3, on which
recent discussion has presented inaccurate information.
1. The FSF has no power to force anyone to switch from GPLv2 to GPLv3
on their own code. We intentionally wrote GPLv2 (and GPLv1) so we
would not have this power. Software developers will continue to
have the right to use GPLv2 for their code after GPLv3 is
published, and we will respect their decisions.
2. In order to honor freedom 0, your freedom to run the program as
you wish, a free software license may not contain "use
restrictions" that would restrict what you can do with it.
Contrary to what some have said, the GPLv3 draft has no use
restrictions, and the final version won't either.
GPLv3 will prohibit certain distribution practices which restrict
users' freedom to modify the code. We hope this policy will
thwart the ways some companies wish to "use" free software --
namely, distributing it to you while controlling what you can do
with it. This policy is not a "use restriction": it doesn't
restrict how they, or you, can run the program; it doesn't
restrict what they, or you, can make the program do. Rather it
ensures you, as a user, are as free as they are.
3. Where GPLv2 relies on an implicit patent license, which depends on
US law, GPLv3 contains an explicit patent license that does the
same job internationally.
Contrary to what some have said, GPLv3 will not cause a company to
"lose its entire [software] patent portfolio". It simply says
that if someone has a patent covering XYZ, and distributes a
GPL-covered program to do XYZ, he can't sue the program's
subsequent users, redistributors and improvers for doing XYZ with
their own versions of that program. This has no effect on other
patents which that program does not implement.
Software patents attack the freedom of all software developers and
users; their only legitimate use is to deter aggression using
software patents. Therefore, if we could abolish every entity's
entire portfolio of software patents tomorrow, we would jump at
the chance. But it isn't possible for a software license such as
the GNU GPL to achieve such a result.
We do, however, hope that GPL v3 can solve a part of the patent
problem. The FSF is now negotiating with organizations holding
substantial patent inventories, trying to mediate between their
conflicting "extreme" positions. We hope to work out the precise
details of the explicit patent license so as to free software
developers from patent aggression under a substantial fraction of
software patents. To fully protect software developers and users
from software patents will, however, require changes in patent law.
I think it's well worth visiting http://gplv3.fsf.org and signing up to
the list to get stuff like this.
