In what way is it anti-competitive? Google's competitors also consume AMP pages and prerender them using AMP caches. Anti-competitive would be requiring the publishers to integrate directly with Google like Apple News, not asking the publishers to publish pages that all link aggregators can consume.
I'm confused, you make it sound like a free CDN is somehow a bad thing. You do realize people actually pay money to have their content on a CDN. I don't think Bing makes money on their AMP cache, and doubt they would want or even allow Google to link to content on their AMP cache...
The point of AMP cache is for Google (and Bing) to waste money making content faster for their users, in the hope that the user will then spend more time on search so they see more ads. The cache itself has nothing to do with the monopoly, and the fact that Bing can use AMP at all (since its open source) to get the same benefits actually shows the exact opposite.
> Google Search uses its monopoly to push their own AMP cache. I can't search in Google and load the content through Bing's AMP cache.
That's nonsensical. That would reveal what the person searched for to a third party (Microsoft) even if they don't click on any results. The AMP Cache has to be controlled by the link aggregator in order to support safe prerendering, so Bing's AMP cache is used to prerender Bing results, and Google's AMP cache is used to prerender Google results. Compare to directly integrating with Google, in which case, Bing wouldn't get to take advantage of prerendering. The latter (the Apple News setup) is anti-competitive. AMP is not.
