The headline is an outright lie: these AMP pages are loaded from Google and not your domain. The new feature is that Google's browser displays your domain, obscuring the fact that Google is doing the serving. The change is what is displayed, not the server.
So Google’s browser now directly lie to the user about what’s being loaded?
I bet the SSL mark is still there though?
How can anyone trust this Googlan horse?
This is why you don’t make a browser and control major web-assets at the same time. These lines should not be muddied.
