From the New York Times:
The Federal Communications Commission formally voted Friday to uphold the complaint against Comcast, the nation’s largest cable company, saying that it had illegally inhibited users of its high-speed Internet service from using popular file-sharing software. The decision, which imposes no fine, requires Comcast to end such blocking this year.
Kevin J. Martin, the commission’s chairman, said the order was meant to set a precedent that Internet providers, and indeed all communications companies, could not keep customers from using their networks the way they see fit unless there is a good reason.
