An anonymous reader writes: The music industry has long argued that evidence of BitTorrent is evidence of piracy, and ISPs have generally gone along with them. But now, ISP Cox Communications is pushing back against that claim. They have been sued by publishers for failing to halt service for users alleged to have pirated music. Not only has Cox argued that the piracy evidence is invalid, they're also contesting the idea that BitTorrent is only used for piracy (PDF). "Instead of generalizing BitTorrent traffic as copyright infringement, the music companies should offer direct proof that Cox subscribers pirated their work. Any other allegations are inappropriate and misleading according to Cox." The company says, "the Court should preclude Plaintiffs from relying on mere innuendo that BitTorrent inherently allows individuals to infringe Plaintiffs' copyrights."
