EFF is urging a federal judge to reject a porn troll’s ploy to make a Wi-Fi provider responsible for the purported copyright infringement of another user.  Liberty Media Holdings (LMH) is suing two roommates in New York, alleging the illegal downloading of a pornographic film, even though LMH argues that only one made the infringing copy.  Remarkably, LMH claims that the non-downloading roommate is also responsible for copyright infringement, simply because the Internet subscription is in his name and that he might have known his roommate sometimes made illegal downloads.
