I see this attitude, but don't understand it. It seems based on a view that more software is always better, no matter how it comes in to being. But of course, attacking the legal constructs under which assumptions people create software means fewer people would create it in the first place. It is privileging parasites over the host.
And the attitude is almost always myopically limited to the GPL. Would you react the same way to a suit that substituted the infringement of Microsoft copyright? "Microsoft sued someone for infringing their copyright, so now I'm scared to link their code" doesn't pass the giggle test.
