Anti-trust isn't relevant. Cable companies have been locking consumers in for decades without ever having to run afoul of anti-trust laws. You talk about enforcement but what we're facing is a loss of any hope for enforcement. The NCTA is pushing their faux "consumer choice" as an excuse for the FCC to gut the regulations that have at least forced things to the point where just about any cable customer can buy a CableCard device and expect that it will work even if it's a hassle. That wasn't the case not so many years ago.
