AT&T, Comcast and T-Mobile were recently slapped down by the courts for trying to bury language in your terms of service that would limit your legal rights. The companies have tried to force consumers to take place in mandatory arbitration instead of having their grievances heard in a court of law. Not surprisingly, arbitration almost always rules against you.

The primary goal is to prevent you from participating in a class action lawsuit against your provider -- say, for forging TCP packets (court pdf) in order to slow upstream p2p traffic. The Consumerist notes that Comcast customers have another opportunity to opt-out of arbitration via this months bill -- simply head to this Comcast website and enter your information.
