In part that's what the courts are for, if the FCC pushes the ISPs beyond their mandate the ISPs have *plenty* of budget to push back (and will, pretty much guaranteed, no mater what), I'm not exactly weeping over AT&T's legal budget, no one is starving in Verizon's C-suite, etc. In the other direction there's quite a few watchdog orgs for consumers on this end of things, including the EFF and the ACLU.
And on that note, I have to ask, NN puts restrictions on the ISPs ability to discriminate traffic based on source and sink, what *government* overreach are you actually worried about here? Are you terrified that Comcast's impoverished CEO won't get another massive raise from his $40M compensation because they couldnt force every commercial service to cough up an extra access fee to prioritize their traffic over competitors? The ISPs aren't starving here, and the regulation ensures a level playing field for web based businesses.
It benefits everyone who *isnt* a ISP exec or major shareholder, which, mind you, is by far most of the country, and none of the people I listed need any help right now unlike the rest of the country. It benefits entrepreneurs and normal internet users alike. It benefits American business overall *and* consumers (a nice duo together). The only people who don't like it are the ISPs, and again, they're doing just fine, they just want to squeeze *more* blood from the stone.
Not to mention, of course, as has been discussed to death, this is generally how the internet has always worked, and what the FCC has a long history of trying to enforce, so there's quite a track record to look back at. Also there's the fact that the whole repeal of Net Neutrality is actually happening, people with a viewpoint like you winning (despite lacking support from most ofthe country), which in itself shows a form of "successful" pushback against and "accountability" of the FCC (at least from your perspective).
There's plenty of history there for you to answer this question: What is your *actual* worry with net neutrality beyond vague fear mongering about the government and some quasi libertarian hand waving?
