As a user I've learned to avoid AMP pages because the UX is horrible: * back button is broken 1/2 the time * the bar wastes 1/3 of my screen * I can no longer see what site I am on in the url * it's hard to navigate to the / of the site * I can't forward the link * being on a good network in US it solves no problem that I have What I'd really like to see is a way to opt-out of seeing AMP'ed pages in my search results…
Visiting non-AMP sites on mobile is masochistic (e.g. try searching news results). You get basically all the same problems, but also pop-unders, late loading ads, greedy javascript, autoplaying videos, and other bad behavior. The AMP is really quite solid for the news use case, in my experience.
Non-AMP sites are frequently improved by the reader button. That's how I prefer to read news sites.
