Ok, sure. Going through a slide-show makes total sense. So, you're saying that there's no normal behavior on a plain website for swiping right (yes? I don't use mobile much myself), but AMP adds a Google-centric swipe-right function regardless of whether there would otherwise be no swipe-right function or some other expected one. Am I understanding now?
Yes, that's it. Google hijacks the back button, swipes, and the [X] button on the AMP banner...in favor of Google, and to the detriment of the publisher.
That is indeed horrible. I am glad to learn that there isn't otherwise some new trend of people constantly right-swiping for no apparent reason though.
