Actually, as far as I can tell, they don't. They grant permission to do
specific things which you otherwise have no permission to do (such as
distributing source code). Interestingly, every restriction in the GPL I
could find is merely a restriction on what activities it permits you to do;
they do not restrict your outside activities. If you accept the license,
the things you are then permitted to do are a *strict superset* of the
things you were permitted to do before.
It restricts redistribution. Without the license, you have no permission to
distribute at all. It restricts creation of derivative works. Without the
license, you have no permission to create any. And their distribution.
Without the license, you have no permission to distribute any.
(There might be a different situation if you already had the GPL-licensed
work under a *different* license which granted different permissions,
neither a superset nor a subset of the GPL permission; the interaction
might be tricky to work out and might mean that the GPL required you to
give up some of the other permissions, though I doubt it.)

Yeah, that's contract-like language, true.
There are none so blind as those who will not see.
