DeCSS (DVD decryption software) has been declared “pure speech” by a California court. Sweet! This software breaks the encryption on a DVD so you can play it on a Linux computer. The Motion Picture Association of America have a vested interest in making sure you can only play discs on approved players, and so they’ve been suing in court to prevent people from distributing it or even linking to it. Some people think that’s ridiculous (and I happen to agree). At any rate, it looks like I can wear my DeCSS T-shirt in the U.S. without fear of getting arrested.
