People who

- use iOS 15 (including betas)

- hate AMP

- still use Google for search

- went to the trouble of finding and installing such an extension

is probably a number that rounds to 0.0% of Google searches.

Not meant as a critique of the extension writer, just agree that this explanation seems highly implausible to me.

I agree – the number is probably insignificant, but I don't think you have to restrict your estimate to people who hate AMP. Basically an average iOS user (likely using Google as it's still the default last I checked) who in the past installed an extension to block unwanted content (ads/malware/etc) may be blocking AMP links without even knowing what they are.
