>Content should remain on the publisher's site.
Publishers are free to implement their own cache and host their own content. AMP is open source and they can modify it however they like.

"…but there’s a big catch: if readers decide to share a link to an AMP page they’ve clicked on through a Google search, the link points to Google.com (for example, google.com/amp/yoursite.com/yourpage/amp), not to your site. A Google spokesperson confirms that there isn’t a way to both have your AMP-optimized appear in Google’s prioritized search listings without having that content hosted on Google’s AMP Cache servers."
1. You can (and must) host AMP content on servers of your own choosing.
2. Google's crawlers ingest your AMP content, validate it, and re-host it in Google's AMP Cache. Bing and other folks run similar crawlers and caches.
3. Google search results will only link to AMP content on Google's own cache.
So yes, you can host your content on your own servers. And you can give people direct URLs to that content. But Google users will only ever see links to the copy of your content that Google hosts; your servers never see that traffic.
There is no way to opt-out and still be considered a valid AMP page.
Disclaimer: I work for Google and have some involvement with AMP.
The worse case I've seen is a site in which every page crashed Mobile Safari without fail regardless of which version you ask for. It was eventually fixed but I never figured out why. If the sites are just running some script without checking then the admins have failed their line of duty.
I'm just going to file another complaint to the EU Antitrust committee otherwise, as this is a simple and clear violation. (Although I doubt my own complaint would be very relevant — all large publishers already have filed such complaints, and Google will be fined for it).
My pages actually increased their loadtime tenfold when I tried them with AMP — they're tested on a HUAWEI IDEOS X3 on 64kbps GPRS. AMP increases load time to over a minute. (On a modern phone, with a modern connection, my pages are obviously also faster — I'm also testing with a Nexus 5X on 100Mbps 4G)
I have the choice between a massively worse user experience, or worse search ranking. And that's a choice that's just not acceptable to me.
