As I understand it, the real concern is that ISPs will create "fast lanes" for companies they're friends with, and reduce / stagnate the speed of everything else. Subscribers will be happy with their low base rate because they can stream 4k video from Netflix, yet your video startup will fail because of relatively poor performance or will have to pay a ransom to the ISP gatekeepers. Peer to peer applications would be hit just as hard, because they wouldn't be fast laned.
