Incredible Hubris by Comcast. They seem to have no fears whatsoever of a public backlash or retaliation by the Blazers. Perhaps their aquisition of NBC has given them and their legal department a sense of invincibility.
Why would they care? They paid the Blazers 120 million for the broadcast rights, and aside from a handful of people (and I do mean a handful) dumping their Comcast cable subscriptions in protest, where's the harm to them pursuing this particular business plan? If this isn't hurting their bottom line then there is no way they'll budge -- nor care.
