"This webpage works best in Our Browser™️" was just a pointer to the user for a faster experience. It came at the small cost of crippling the web for a mere 15 years, probably costing a few billion hours user time wasted at horrible UX bred in a hostile corporate controlled environment.
AMP is just the same all over again, just with a singular player which might just be too big to fail. Oh, and also this time things like the information source of the western world is at stake, not only fan sites of specific locomotive models by some geeks.
But at least my websites load....slower actually if the page was properly built[1]!
