BUT, because this does force deals to be crafted behind closed doors, they will turn out looking a lot like the deals that HBO/Shotime have with Comcast and TWC. Plus, look at what's going on with Facebook already... phones in some countries have "facebook data" only plans. Sure, this is great for emerging markets to have access to family and friends for free, but at the loss of any other social network upstart that wants in on it.
I don't see indie content ever being cut off, but I do see them becoming "premium" subscription level services that require people to pay more to access them. Want to play COD or GOW online? You will need this level access to play with any reasonable speeds. It will happen slowly too, as people become accustom to the idea that opening a Wikipedia page will take 1000 ms then to 5000 ms to fully finish rendering. Someone at Comcast will nudge slowly testing whether people notice or care.
If we don't fight the good fight and force internet providers to remain dumb pipes, we are asking to have the most expensive internet on the planet. As cable TV dies in favor of watching what you want, when you want, they will naturally move to charge you for things you want to do on the internet instead.
