Cable companies have geographically determined monopolies, especially in Philly and the NJ suburbs. So, blocking Cablevision doesn't help you gain market share as they don't compete with Comcast. But blocking D* and E* IS an antitrust violation in my opinion as they FORCE any Phillie fans to subscribe to cable. If they keep it off DBS then they strengthen their position. This is why Philly is the 4th largest market population wise, but is way down in the teens DBS ratings-wise.
