What they are moaning about...
Probably not, however, it would reduce the need for their services if some of the big players signed up.
Say Sky, BBC and ITV signed up to canvas so you could (With the appropriate subscription), watch news, Sports, movies and such like over Teh Internets!
That would pretty much kill their TV cable service. (And good riddance, cos TBH, their customer services not only seem to not care about their customers, but have an active Hatred)
Of course, crying because their competitors could do distribution better than you is not a valid reason to kill the system, but as any official investigation done by Ofcom is likely to take months, they could at least attempt to throw a spanner in the works.
Unlike the BBC, ITV and Sky, Virgin dont have many channels of their own (Do they have any at all?), and end up reselling Sky, so would be the big loosers if everyone went to Teh Internets for their entertainment rathr than paying them.
