The network owners and TV stations want their cut of the action
Commercials mean nothing because Nielsen doesn't count aps users, so any additional viewers don't translate into higher ratings. If Nielsen can't count you (or doesn't choose to count you), the effect is the same.
TV stations and networks feel you pay the cable bill to get the signal delivered VIA CABLE. If you want an additional delivery method you pay again. It would be like having cable and a dish.
ISP providers are starting to fight back too. AT&T DSL is going to cap monthly downloads at 150gb. Which is ridiculously low considering if you get 5.0mb connection speed how much you could in theory download. I feel if I'm paying for a connection speed of 6.0 and I'm only getting 5.0, I ought to be able to get that 5.0 24/7
Well evidently that isn't going to be the case.
Basically it comes down to if there is money to be made, everyone wants their cut of the profit. What will happen is that the TV stations and networks will reach agreement to receive some money from TWC for streaming and everyone will be happy.
Except for the guys who forget about their ISP cap
