In many ways, I agree. The FSF seems to be barking up the wrong tree, the
real problem is not things like Tivo (who already _do_ give source back),
but the whole "we don't give source back because we're just exporting the
results", aka the "ASP problem".

While I agree with you, I think one of the reasons that the FSF hasn't
gone that way is that while in many cases it would make sense, it's
actually even more controversial. The "Tivo" issue is a populist issue,
and trying to solve the "ASP problem" is actually seriously more
problematic.
First off, the ASP issue, while not in any way limiting "use" (you could
still _use_ things as you see fit, you just have to give sources out: I
think that's much more "in the spirit" than the current GPLv3 ever is),
would actually require that in order to enforce it, such a license would
clearly have to be a _contract_. If it's not distributed, it's not a
matter of copyright any more, it's very obviously a matter of mutual
agreement: "we give you source, you give us source back".
Secondly, a lot of people use GPL code privately, with private
modifications, and you would see a lot more screaming than about the
current GPLv3 draft. So I think the FSF (correctly) decided that they
simply cannot do it.
In fact, it's one of the very traditional ways of making money for some
Free Software projects: the whole way Cygnus supported itself was largely
to make "private" branches of GCC for various commercial vendors, and
while the vendors had the _right_ to distribute the sources, they also had
the right not to (and since they didn't want to, they wouldn't be
distributed).
Does that sound against the spirit of "give back source"? Sure does. But
it's one of those things that the FSF has always supported, so they don't
see it as a huge problem, and since they don't want to limit _that_ kind
of usage, they automatically also cannot limit the ASP kind of usage which
really is exactly the same thing.
So I actually think that an ASP clause would be totally unacceptable to a
lot of people, even more so than the stupid anti-Tivo clauses. And I think
the FSF realized that, and didn't even push it, even though they have been
talking about the "ASP hole" when they don't like it.
So it really does boil down to a very simple end result (which is the
exact same deal that I think the whole anti-DRM problem has been about):
- Not everybody agrees about the current GPLv2
- But trying to extend the reach of it just causes more (fundamental)
problems than the problems such extensions would try to fix.
So I'd like to repeat: the reason the GPLv2 is wonderful is exactly the
fact that it's so widely applicable, and useful for such a wide audience.
That _does_ mean that it will inevitably have to accept a certain level of
bad behaviour by selfish people, but since you can't distribute the
derived work without distributing the source code, you're guaranteed that
the bad behaviour cannot "procreate".
In other words: if you think of open source development as a kind of
"sexual reproduction" (it really does have a lot of analogies - it's a
"memetic recombination and survival of the fittest"), any "bad use" by
definition is a dead end. You can be bad, but a bad use is always a
eunuch, and as such doesn't matter in the long run. The only way you can
actually make a _difference_ is by participating constructively.
In other words: I do agree that the "ASP hole" is a hole, but exactly as
with all the Tivo issues, it's a hole that needs to be there simply
because trying to plug it would cause disaster.
