I don't disagree with you, but there are so many bad websites that something should be done. AMP is a really bad solution to a real problem. Walled garden pages as Facebook for companies and similars are equally bad in my opinion. Some time ago I had the idea that, maybe, the website layout could be controlled by the user, and only data are controlled by the website's owner. The web would become boring, I know, but the alternative is just as bad: broken websites.
