You seem pretty pro-free-market, so here's the free-market angle: things like zero-rated Netflix on your mobile plan and free "basic" internet are market distortions. Companies are abusing the lack of net neutrality to engage in bundling, discounting, and collusion practices, which are bad for you as a consumer - these are anti-competitive practices!
Everyone likes getting something for cheap/free, but that doesn't mean that it's actually good for you, other people, the market, or society as a whole.
I agree that most of the bad things that net neutrality advocates predicted would happen wouldn't, but the things that did happen are still bad.
