We're not sure what took so long, but the MPAA just announced that major movie studios (Fox, Disney, Paramount, Universal, Columbia and Warner) have filed a civil lawsuit against former filesharing site Megaupload and the people who ran it. This comes over two years after federal investigators shut down the website, seized its files and filed criminal charges against founder Kim Dotcom aka Kim Schmitz. MPAA lawyer Steven Fabrizio (named its global general counsel late last year, he's won cases against Hotfile and IsoHunt) claims that at the time of its shutdown, Megaupload was "by all estimates the largest and most active infringing website targeting creative content in the world." Specifically targeting the site's Uploader Rewards program, the claim is that its business model was "designed to encourage theft." According to Dotcom, the rewards program was terminated six months prior to the site's shutdown, and Megaupload continued to grow without it.
