Right but that’s not a secret back door tracking mechanism. It’s a pretty blatant one!

My point is that even this blatant logged in user tracking won’t be able to use user agent strings to track either.

you're the one who introduced the concept of it being secret, your quote just said they have access

    There is no publicly known method by which Google’s ad network is able to siphon extra data from Chrome users for targeting etc. If there is one, as OP’s friend suggested, definitionally it must be secret.
