I'm not sure I follow how Google helped create a trend of increasingly bloated sites that don't load quickly? The only sites I see loading remotely as quickly as AMP sites are AMP sites. Nothing comes close, nor is it apparent online publishers are even trying to optimize their pages to load quickly. AMP strikes me as a project of desperation by Google, as publishers seem intent to kill their own sites by loading them with as many XML HTTP requests and trackers as possible.
