Having AMP controlled and intermediated by Google was always a bad thing. It tainted what ultimately was a good effort, which is taking the enormous scope of web technologies we have now and winnowing them back down again for optimized publishing purposes. And this article does what is often done in the AMP discussion and (disingenuously) demonstrates that you can make a non-AMP page that's smaller/faster than an AMP…
1) Google clearly leveraging it to take over more of the web,
2) The scroll hijacking that made it feel worse-performing (plus just otherwise unpleasant) than middle-weight websites normally do,
3) That some of the sites I most commonly accidentally end up viewing through AMP are useless in their AMP version, so it just adds a hunt-and-click for no reason (Reddit is a big offender)
Google is one problem, one is a technical implementation problem, and the other is an ecosystem problem.
