It breaks most sites I use, unfairly promotes sites buying in toward the top, and I spend more data, time, and frustration than I would otherwise because I need to proceed to the actual page to get what I need.

It’s a pure negative.

Waiting for Apple to introduce a 'show originals rather than AMP' default into iOS Safari.

This feels inevitable, culminating in "Default Reader Mode." It makes one wonder why Google didn't bury some option to disable AMP to head this off.

This exactly...So frustrating clicking a web page and then inside the webpage parts of it are broken because you are actually at the amp site not the actual site. I haven't looked at how I can just avoid amp sites all together but if I had the choice I would.
