In the past, people getting really mad at ISPs has not changed anything. I don't see any reason to believe that people getting really really REALLY mad is going to change anything either. There's no mechanism for it to.
The customers revolting is not a matter of influencing Comcast/ATT/etc, it's a matter of influencing Google/Apple/HBO+Disney/Netflix etc etc etc.
People love to trivialise this counter-point as merely "oh ISPs dont have competition therefore the market can't fight this problem", which is incredibly reductive and misses the forest for the trees.
