And, in particular, it has the right meaning for what we're trying to talk
about. I'm not following why you don't want to use that word, when it seems
to be clearly the right one for what we're dicussing. It's the GNU General
Public _License_ after all.

A license is a grant of permission. We're talking about grants of
permission, so license is the right word. There's no need to make this
harder than it is.

I don't think I've claimed that yet, actually. I'm not sure I will, either.

It's not a crime to violate a license.
Here: "I hereby give you a license to breathe air, as long as you pay me
$50."
You can choose to not abide by that license (by, eg, breathing without
paying me $50), but that doesn't make it illegal. If we'd made a contract
that only allowed you to breathe if you paid me $50 (there'd need to be
some other consideration for you though for it to be a valid contract),
then if you didn't abide by that contract, you'd have violated the
contract and be liable for damages and such.

Not abiding by something doesn't have any negative connotatons -- you're
not particularly going to get punished. Violating something has the
connotation that you're doing something bad and will be punished, OTOH.
So I'm inclined to think talking about "violating licenses" is likely to
just lead to misconceptions, rather than clearing them up, especially when
a work might be available under multiple licenses.

Who can sue whom is a matter of local law, and isn't a matter that
particularly interests me, to be honest. The only thing that's really
interesting is if anyone can sue me, or if no one can.
If Alice gives a copy of some program she wrote to Bob, with a license
that lets him sublicense as he wishes (possibly under certain conditions
like retaining her name and copyright statement), and he then sublicenses
that to Carol under the GPL (but abiding by Alice's conditions), and
Carol then uploads to Debian, neither Carol nor Debian can be sued,
as long as they abide by the GPL.

One possibility:
Alice wrote foo.c, licensed under the GNU X11 license.
Bob wrote bar.c, and distributes FooBar.tgz, including foo.c and bar.c,
and distributes the entire work under the GPL. He doesn't need to obey
the GPL (he holds the copyright to foo.c) and thus can't violate it,
so it doesn't matter, so the only possiblity here is if the GNU X11
copyright is violated. It might be if Bob claims to have sublicensed
the work, and isn't allowed to. It's not clear to me whether that is
allowed or not.
A better possibility:
Alice wrote foo.c, licensed under the GNU X11 license.
Bob wrote bar.c, licensed under the GNU GPL.
Carol writes baz.c, and builds /usr/bin/baz by statically linking each of
foo.o, bar.o, and baz.o. This time, Carol has to abide by both the
GPL and the "X11" license. The GPL says she "must cause [the work]
to be licensed as a whole at no charge to all third parties under
the terms of this license". That doesn't require her to license
baz.c like that, but it does require her to license /usr/bin/baz
like that. As this is a derived work based on foo.c, the question
is, can she do this? If not, she's either doing the same thing as
Bob did last time and misrepresenting her ability to sublicense
works based on foo.c and infringing on Alice's copyright, or she's
not abiding by the terms of the GPL (ie, not licensing the work as
a whole in the proper way), and thus infringing on Bob's copyright.

No: sublicensing something that's already licensed to the public at large
doesn't revoke the original license.
More particularly: if I give you a copy of a GPLed program, I'm exercising
my rights under the GPL (my license, if you will). But you may've already
received a license to do stuff to that program --- indeed you may have
received more rights than I had in the first place. That you got a copy from
me means *nothing*.
To put it another way, distribution of license, and distribution of
"physical" bits are independent. I can give you a copy of a program
without giving you the same rights to it I have (if I wrote it, or if
I'm allowed to sublicense it), and you can obtain rights to code I've
given you independently of me (I'm I'm not the author, or if I've allowed
others to sublicense it).

Why do you think I've ever seen a precise definition of sublicensing?
Alternately, where's your precise definition of sublicensing that you think
it's an impossible thing to do wrt copyright?

The FSF could be wrong, of course. It's not impossible.
In particular, AIUI, rms and the FSF believe the last clause from the
OpenSSL license makes that license GPL incompatible. To quote Aaron
Lehmann (giving advice from an unnamed friend) from a few weeks ago on
this list:
] In summary, the clause:
]
] * The licence and distribution terms for any publically available version or
] * derivative of this code cannot be changed. i.e. this code cannot simply be
] * copied and put under another distribution licence
] * [including the GNU Public Licence.]
]
] ...is a no-op, as copyright law already implicity provides it. This
] clause does not cause much reason for concern.
It seems to me that if this is true (that is, sublicensing, like
modification and distribution, is reserved to the original copyright
holder), then this doesn't say anything more than what's already implied
by, say, the GNU X11 license.
OTOH, the BSD license (/usr/share/common-licenses/BSD) also doesn't
specifically let you derivative works under other terms, but BSD-licensed
software frequently is distributed under other terms, collectively at
least, such as its inclusion in Windows.
If you're not allowed to relicense a work, or a derivative work unless
you get explicit permission, should the FreeBSD project sue Microsoft
just for the heck of it? Could they?
If you aren't allowed to relicense a work, how can you cause a derived
work comprising BSD code to be licensed under any terms other than the
BSD license? Can you do it just by running a compiler/translator over it?
How about writing some of your own code? What if your own code is under
the GPL? What if it includes other code under the GPL? If you can cause
the derived work to be licensed as a whole under the GPL, why can't you
cause the original components to have the same thing done to them?
(Personally, I'm not convinced that the right to sublicense is quite as
reserved as Aaron's friend makes out. That seems the only way to make
sense of this. Well, another way is to consider the BSD's frequent
assertions that you can take BSD code and make it proprietry as an
additional license; and the FSF's webpage as non-authoritive...)
