I agree it's a very difficult definition.  I'm not sure I'm happy with
the wording in place right now.  But I very much like and agree with
its purpose, and it is in line with the goal of respecting and
defending users' freedoms, which is what the FSF cares mostly about,
and must care about, because it's its official and public mission.

That's what I care about, and I've seen false claims that it does.

Can you please acknowledge that it doesn't, such that I can feel I've
fulfilled my goal of dispelling the myth that the GPLv3 changes the
spirit of the GPL?

Is it correct to say that you share Linus' opinion, that the only
problem with the GPLv3 is the anti-tivoization provision?

To make this more concrete, if there was a hypothetical GPLv2.9,
consisting of GPLv3dd4 minus the "installation information"
requirements for user products, (i) Would you consider it a better
license than GPLv2?  (ii) Better for Linux?  (iii) Enough to go
through the trouble of switching?

I'd love answers to these 3 questions from others too.

Just in case, I shall point out, one more time, that I'm speaking for
myself, not for the FSF, not for FSFLA, not for Red Hat.  The
questions above are to satisfy my personal curiosity.  I don't make
any commitment whatsoever to take the answers up to the FSF, and I
don't want to set any expectations as to whether they could or would
make any difference, at this point, about the outcome of GPLv3.

If you want your opinions to stand a chance to make a difference, the
right place to provide them is gplv3.fsf.org/comments, and time is
running short.
