Several major Hollywood studios and record labels have filed an appeal with the U.S. Supreme Court of a recent federal court decision which held that the makers of file-swapping software are not liable for the illegal actions of their customers. Free speech advocates are encouraging the high court not to review the case, saying that it represents a direct attempt to intimidate software makers and the public. There are also timing questions surrounding the petition, which was filed after the controversial Induce Act stalled in the U.S. Senate last week.
