AT&T did a similar thing when people were going DSL-only. I had AT&T DSL + phone line and called to cancel the phone line, they gave me the phone line for 12 months at $5 a month simply so they could show their shareholders that people weren't cutting the cord. That was cheaper than the VOIP provider I was planning on going with, so I stuck with it another year, didn't really use it though.
Cable's user experience is horrible, it's terribly expensive, it's price grows many times the rate of inflation, users feel screwed because they are forced to buy packages of channels they have no interest in, and feel forced to "bundle" to feel less screwed.
Comcast regularly wins the "Worse Company of the Year" award, and has terrible customer experiences.
None of Cable's deficiencies have anything to do with Netflix or Hulu. In the end, the thing that kills Cable won't be Netflix or Hulu, it will be Cable that kills Cable. The Cable industry are pigs which will soon get slaughtered by their own greedy hands.
Netflix and Hulu are just there to pick up the pieces.
> What about cable without cable TV?
This still doesn't exist yet. Even for HBO GO access, Comcast still forces you to be a basic cable subscriber.
