I've never really felt much obligation to obey laws that I find to be moronic. I can't speak for anyone else, or any other country, but here in the states, the copyright system (and the patent system, for that matter) are fundamentally broken.
Don't take this the wrong way, I can and do respect reasonable copyright, within limits. (And I certainly respect the rights of a website like Amiga.org to not have people linking questionable content in their forums.) The problem is, all reason has been lost here in the states, and the MPAA, the RIAA, etc., are all running amok, trying to prop up business models that have been slowly dying for 8+ years now. The software guys aren't that bad as the music and movie guys, but expecting me to feel guilty about copying a game that hasn't been financially relevant to a company for 15-20 years isn't going to happen.
