The take is absolutely coherent:
JavaScript based ad/analytics tech is bloating the web. Everyone knows this, and there's no denying it. Google is one of the main advertising/analytics platforms on the web. Google is aware that JS is poisoning the web, but they don't want to kill the golden goose and they do want to entrench their ad monopoly. How to square the circle?
They should but won't just tell advertisers that creatives need to be static image/video assets, thereby saving bandwidth, protecting privacy, and not really doing anything to ad buyers (because ad buyers are driven by their fixed budgets and not by absolute platform capabilities, just relative capabilities). Since that's too risky to Google's core business, instead they create a new format (AMP) with deliberately limited JS capabilities and, oh yeah, built in support for Google ads.
For everyone who is not Google, this solution sucks. It means duplicate work to create a new format, the new format is different than the web but not a meaningful source of new traffic because it's just a splinter of existing traffic, and it further exposes your business to Google as the core gatekeeper of revenue (FaceBook is the other revenue gatekeeper). That is, you need Google search and Google ad money to survive and if they change the search algo or ad rates (ie now ads need to be videos or now ads need viewability or whatever), you can be crushed without notice.
