Except none of it happened. It turns out there's actually kind of okay competition in this space. Maybe not as much as there should be, but prices have stayed reasonable, broadband access is expanding, and people by and large don't seem bothered by data caps when they're subject to them, and they have access to reasonably priced, uncapped plans.
All that said, I certainly won't say no to reinstating net neutrality, since I don't think you can argue it'll make anything worse. In fact it might make competition easier. But it's not the existential pillar to online existence that we seemed to think it was.
