Well, speaking as a web user, I hate AMP, and actively avoid websites where there's no other option. The reasons? Most of all, I don't like how they break the Back button in strange ways (I still haven't figured out how exactly it's supposed to operate, but it's certainly not working as it usually does in a web browser). And I don't like that all URLs are showing up as Google.

In abstract, I also don't like the notion of giving Google that much power. Even if what you say makes sense, and regulation is necessary, a private company doing it is the worst of both worlds - they are not accountable to the rest of us, and they have their own goals that contradict the public good.
