This is a bit like removing a traffic light from an intersection and then after a day saying "see, nothing happened, we don't need regulation from traffic lights". Laissez faire, everything will be alright.
ISPs don't exist in a vacuum. Why would Comcast spend millions of dollars implementing some anti-NN consumer ratfuckery when they'd have to revert it once the next administration came into power? If Comcast knew that it wasn't going to get overturned, then they would take advantage.

We shouldn't have waited at all, and in fact shouldn't have allowed it to be repealed in the first place. We have been extraordinarily lucky to have not had to deal with any nonsense from ISPs in all this time. California having their own NN law helped a lot. Now that we're back on track we can call it crisis averted, no harm no foul.
