Looks like the copyright wars regarding YouTube have gotten hotter. Not only have we learned today that NBC Universal and Fox plan on launching a rival video site (gee, I wonder if they allow users to upload or feature critical content of themselves ) but that Viacom is using the DMCA to trample the First Amendment and Fair Use.
MoveOn and the Electronic Frontier Foundation have joined forces to sue Viacom in reaction to the company using the DMCA to compel YouTube to pull clips of Colbert episodes that were part of a MoveOn and Brave News Films (which is part of the suit) documentary "Stop the Falsiness" which is a "mockumentary" of the show.
Viacom's defense is that they never sent a take down notice, despite the fact that YouTube has identified Viacom as the source for it.
I don't exactly see this suit as one that will change the course of copyright law, but I'm glad to see Viacom squirm for once, instead of trying to act like the RIAA and be a dick to its fans who post the clips (why do you think those Colbert clips are so popular?)
