Quite a few somewhat controversial movies are in cinemas these days (Rendition, American Gangster, Juno, The Kingdom) - so perhaps you should not cram the entire industry into a box that only fits the Adam Sandler genre.
That said, I agree completely that this is a lost fight. As stated by Dan Glickman (Chairman, MPAA) in "Steal This Movie II", they realize they will never stop piracy - they just "have to try to make it as difficult and tedious as possible". The first question that pops into my head is whether they really and honestly believe creating the greatest PR possible for sites like the bay is effective in achieving this goal. To my knowledge, stunts like this hasn't exactly worked in their favor in the past.
