The article is wrong, as no amount of preloading will make the non-amp Verge fast to load as it runs too much JS to block the initial render. You could provide a mobile framework and tools for publishers that helps sites create pages that render fast by putting them on rails. AMP is that framework, other people could similarly introduce tools to help. Chrome DevTools and Google has long offered the Page Speed tools a…
You're missing the entire point. It is fine to have a framework like AMP that puts up technical constraints leading to a performance-friendly web page. The problem is the cache and specifically the preloading of it. This gives AMP an unfair advantage of multiple seconds over anything else.
Still, even without the AMP-cache, mobile sites were loading way too much JS, even after Google penalized them. The effect of AMP showing how sites could be loaded as fast as native Apple News/Facebook Instant, has finally gotten publishers to strip down their sites. You might not like the way it played out, but the end result is that not only do end users get AMP-cached fast loading, but they also end up download far less data, because the sites themselves have been pared down.
