Also, the parent said there was many things the GP could do, while the GP was talking about as an end user, not a developer. As an end user if my choice is between a fast smooth sleek amp page or a 10 second blank screen and a page that hides the content, has autoplaying videos, and required me to dismiss a 1/3 cookie banner, I'm going to pick the amp version.
