Well, it's the going opinion of HN for years that the main problem with AMP is it shows the actual origin instead of the proxied origin. Lying about the URL is something hundreds of HN comments have angrily demanded.
Why do you say that? I don’t think people want it to show the “proxied origin”, they want AMP to get out of the way and google to link to the real website.
This is not correct. Anyone can host AMP. See, for example, amp.cnn.com. Google hosts AMP content for its customers who elect to use that service. It’s not a nefarious plot.
