Megaupload founder Kim Dotcom is often described as being most effective at trolling the entire entertainment industry. So why not fight fire with fire? Dotcom got a dose of his own winding-up medicine yesterday when a video of the launch party for his new Mega service was removed from YouTube due to a copyright takedown request from German collecting society GEMA. “Incredible: The GEMA in Germany took down our #Mega launch press conference video from Youtube for copyright claims,” tweeted an outraged Dotcom. “Dear GEMA, all songs in the #Mega press conference are my content. And the artist who performed LIVE gave us permission. WTF?” Dotcom added that he had filed a counter-claim with YouTube to get the video back online, and warned that “GEMA can expect mail from our legal team”. This should be fun.
