AMP made the internet on my phone work. Most sites seem to dedicate 50% or more of the screen space to advertisements and load very slowly -- AMP sites were just crazy more performant -- I'm not saying AMP was the right move to make, but, it was trying to solve a real problem (similar to this bill also likely being the wrong move)
AMP worked like shit for me. Any time I had weird behavioural issues with a site, I’d look to the address bar and spot AMP. Using an extensions to prevent AMP stealing my clicks has made my phones browser work much better.
