It's solely the search engine boost you get from AMP that bothers me. Because of the money involved many sites have no choice but to implement AMP and stay competitive. If it weren't for that, it would just be another technology and the fact that it only works in few circumstances would probably make many sites not bother with it. The UX downsides would probably see many sites actively avoid it.

The fact that it has seen such adoption is testament to Google's ability to influence with it's rankings alone.

Have you noticed ranking improvements? We've done AMP on some sites and not others and we saw no difference in ranking.

Sure, having a very quickly opened page is nice, but on the other hand, features are limited. That might or might not work well, depending on what kind of content you have, what engagement you're looking for.
