Of course there is a copyright on P. It belongs to A.

Which is perfectly fine, because all of those people explicitly
have the right to download L. There isn't even minor breach of
copyright going on in the B does.

So? The only act protected by copyright is copying. A is doing none

He doesn't. None of the copies made in the scenario are illegal.

Which copy, precisely, do you think is illegal. The GPL explicitly
allows B to derive a non-free program from the library - he just
cannot *distribute* that no-free derived program, and he doesn't.

I'm not. I'm pointing out that those people (B) are explicitly
*allowed* by the GPL to create the copies they create.
