>So, is it possible that Google has given up on AMP in Safari on iOS 15 because of the popularity of AMP blocking extensions?<p>This doesn't make any sense. If AMP is strictly beneficial for google, why would google give up because of a few people with AMP blocking extensions? Surely it's still worth going after the stragglers? You don't see them giving up on ads just because adblock is popular.<p>I suspect the reason is far more benign: AMP is enabled on a whitelist basis, and they haven't whitelisted ios 15 yet.
