That's somewhat simplistic. Peering that's somewhat one-sided can have fees built into one side. Still, getting a large chunk of your content quicker and without overloading your other peers or upstreams means that Netflix and the like should have the power here, and if they desired could charge for this better access (it is one-sided, as mentioned before). It's totally backwards that Comcast/Verizon would be throttling them instead, and is only possible because they don't really compete in a fully open market.
