Why do you insist on making sites being literally shut down the hill on which you'll fight and die?
The more realistic scenario is favoritism. AT&T tries to buy time Warner so they get HBO so that HBO runs at 4K on their network and 720P on everyone else's. Hulu pays Verizon to have higher priority over Netflix on their network. Comcast makes Google pay them to not constantly throttle Youtube. It's stupid. They just want to keep getting paid again for the same service they've already been doing, and they're going to try to deliberately worsen their service in order to then charge for the privilege of not making it so shitty again.
Also, (and not technically NN) see data caps. What's the only reason for them? To force customers who watch a lot of video to pony up for cable instead of remaining cord-cutters.
Corporations are not your friends, and they will fuck you over every chance they get. Simple fact. If they also refuse to compete, we need regulation. Thus, NN. Which again, simply means that it doesn't matter if I'm downloading a Steam game or a movie from iTunes or reinstalling Windows, my ISP shouldn't treat my download differently depending on what kind of info it is. It literally doesn't matter to their system because it's all 1s and 0s. The only reason to differentiate is to try to get paid more than once for performing a service.
