Yes.  Anyone feels like enforcing the GPLv2 in Brazil?  I can even
recommend lawyers that speak English reasonably well and are somewhat
familiar with the GPL, and I've already tracked the distribution chain
back to the initial infringer.  Harald is aware of the issue, but
AFAIK he's decided not to pursue that yet.

There's no reason to assume it's a modification.  They're distributing
a copy, and that's enough.

I'm told by the authors of GPLv3dd4 that this case is not meant to be
permitted.  I suppose they're going to change the wording, or at least
the rationale for it.

This is true.  They didn't have any such duty, under the GPLv2.

However, if I figured that out by myself, but found that I was unable
to run a modified version because something in there checks for a hash
computed over the program I'd like to modify, and refuses to run it
because of the hash, then the hash is effectively part of the program,
and they haven't provided me with the corresponding sources of that
portion of the program.

I know you don't want that to be true, and a court might actually
decide your way some day.  But until then, your claim that this is
permitted by the GPL is just as good as mine that it's not.  And I
really mean "just as good", since my claim is in line with the stated
purpose of the authors of the GPL, and yours is in line with their
opinion (according to others, I don't think I've got this straight
from them) as to whether the license effectively prohibits this
practice.

Actually, this is false.  Not only because of the ROM provisions in
the GPLv3, but because the law requirements aren't anywhere as strict
as the WiFi vendors who want to disrespect your freedoms want you to
believe.

It doesn't.  Authors can always grant these options separately if they
want to.  Authors can always choose GPLv2 if they want to.

GPLv3 is an option for those who want to defend freedoms, even if they
don't share the perception that this is a moral and ethical issue.  If
they're in it only for the self benefits, that's fine, GPLv3 can get
them that, even better than GPLv2 could, in spite of the short-sighted
claims to the contrary.

That's not the goal.
