Comcast's reputation as the worst company in America is well earned. No company in a competitive environment would dare to withhold services for which its customers had already paid. Comcast is shameless, and it gets away with it only because its customers have no other choice. Unfortunately, I am one of them.
The moment Fios or DirecTV or Dish or any other cable company is available to me, I will switch. Even if those services are only marginally better than Comcast, and even if they are more expensive, I will be overjoyed to be giving my money to ANYONE other than Comcast.
