Huh, weird, it's almost like they're abusing their search monopoly to push a technology that everyone hates and is only fast when compared to their ad monopoly.
There are users in this thread that seem to like it quite a lot because it's faster than the original site, because it limits the amount of crap the original site can run. The only reason I don't like AMP is because I don't like an intermediary like Google rendering pages for me and probably tracking what I do on them. That's ... not even close to something on most people's radars, so there's no way "everyone" hates it for that reason.
I suspect most people have never heard of AMP and just like it when sites load fast.
