You have a group of film producers that glorify theft, violence, murder and other heinous acts (many of which are morally questionable) in their films for the "entertainment" of the end users. Do you really think consumers are particularly thinking about content producers copyright when they're getting images of decapitation and bloodshed force fed to them?
Or to use their own campaigns against them - http://www.youtube.com/watch?v=HmZm8vNHBSU
"you wouldn't steal a car" - no, but stealing 50 (aka, gone in sixty seconds) is ok. In fact, Hollywood frames the car thief's actions as a noble thing.
Personally, I don't think people should pirate stuff (even though it's been happening for longer than the internet has been readily available), but the Pandora's box HAS been opened - it's out there now and we're only seeing filesharing becoming more widespread.
Rather than fighting a losing battle, they should instead focus on providing a viable alternative.
Instead of trying to stop those consumers who will never pay for content, why not make it stupidly easy for those who will to do so.
The music industry caught on, unfortunately the Film/TV industry's ships are still sinking.
