Users like pages that load instantly, which AMP is a requirement for (via preloading).
AMP pages loaded through Google search with hot cache load slower than some of the websites I've developed when loaded with cold cache. It's absurdly slow, uses tons of unnecessary JS, and it is a privacy nightmare because now I can't just use server-side GDPR and ePrivacy guideline compliant analytics anymore, but either have to give up analytics entirely, or have to use privacy-obliterating Google Analytics. And if…
On a mobile device in India? Nonsense. Your page load time is dominated by latency, which the AMP user doesn't see because it is preloaded from near caches.
> uses tons of unnecessary JS,
Which of the JS is unnecessary? The JS to load images allows AMP not to preload images below the fold, which is absolutely necessary for speed and for being friendly to data plans.
> now I can't just use server-side GDPR and ePrivacy guideline compliant analytics anymore
Explain. You still get first party tracking that gets fired when the user clicks to your page and can get user consent via data-consent-notification-id.
> And if a user ever loads the page with JS disabled
In that case, it's the SERP's fault for showing the AMP page instead of the non-AMP page. In the normal JavaScript-enabled scenario, the SERP would be stupid to show your non-AMP page.
