True.

It's likely, but not a given.

They're still not obvious no-nos.  For example, any license is subject
to revocation.  Let's say that a copyright holder wrote you a demand
letter saying "I don't think you are abiding by the GPL.  You must
stop redistributing my software."  Your only recourse at that point
would be to sue them.  I have no idea what your grounds for doing so
might be, but that's what you would have to do.

.... and so on.  All of the terms in the APSL 1.2 were defensible
vis-a-vis the FSF's own four freedoms.  That privacy thing I think
Stallman pulled from his butt, though.  It sure wasn't a requirement
before the APSL was published.

Yes, simply because it has gone the other way as well.  We might pull
some requirement from our butts as well, that RMS didn't prohibit.
