You can't even make the argument that AMP degrades privacy, because regardless of whether you click an AMP link or a non-AMP link in the search results, in both cases many search engines will ping back or use a redirect through a search engine-controlled domain, so they will be aware of the URL you click anyway, AMP or non-AMP.
I guess you're making a minor technical point, and it's technically correct. Someone else could do AMP better. But until someone does, why not shorten "Google's implementation of AMP" to simply "AMP"? Is there any other?
I agree that there is a UX problem to solve (the address bar should show the original URL, copying it should preserve the original URL, etc) but whether the webpage got loaded from the original site or from some AMP cache is irrelevant.
> What's in a URL? On the web, a lot - URLs and origins represent, to some extent, trust and ownership of content. When you're reading a New York Times article, a quick glimpse at the URL gives you a level of trust that what you're reading represents the voice of the New York Times. Attribution, brand, and ownership are clear.

> Google AMP Viewer URL: The document displayed in an AMP viewer (e.g., when rendered on the search result page). https://www.google.com/amp/www.example.com/amp.doc.html
Google has inserted itself in the URL. Copy and paste that, submit it to reddit or Hacker News, or just read it to a friend, and what do you get? A connection to Google.
