I like to think about GPL as a kind of an artistic performance and an elaborate critique of the whole concept of copyright.

Like, "we don't like copyright, but since you insist on enforcing it and we can't do anything against it, we will invent a clever way to use your own rules against you".

That is not really the motivation behind GPL licenses. These licenses have been designed to ensure by legal means that anyone can learn from the source code of software, fix bugs on their own, and modify the software to their needs.
