> You'll only ever retrieve Google AMP cache results from the Google search page, where they were already able to track if you made such a request, since the link you clicked has trackers in it. So from that perspective, nothing changes.

I am not affected, I don’t use Google search. The problem is for individuals who use Google search and now don’t have an option to avoid in deep tracking. The difference between regular pixel trackers and multiple data points associated with every resource a site serves is immense. I work in ad-tech, not particularly in the identification side, but I started multiple projects in that end. From experience, a regular tracker can be fooled, but you cannot fool every resource request. One of the things I did to identify ad fraud bots was actually drive them to a site in which I controlled every resource. The resource request fingerprint for bots was easily distinguishable from real people. Moreover, some humans exhibited navigation patterns that were distinguishable from other humans. I remember I caught a QA person doing a shoddy job of testing the front end once due to it. That is the kind of power that Google is acquiring as more and more sites choose to use AMPs. It is scary to think that a single identity has that power.
