Thanks for this - I appreciate you bringing up the scourge that is AMP (triggered)!
"We" (developers) can solve the problem but sadly "we" don't control all the websites. Corporations who own many of the existing large sites have different drivers beyond user experience i.e. profit and throwing in 50 odd scripts to bolster profit is where their heads are at over user experience which is where AMP comes in - honestly or not.
Hopefully over time, as website profit models shift away from advertising (hey, even Zuck mentioned the possibility of a paid version of facebook recently), user experience will get back to number one.
Then AMP will be irrelevant.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
