How do advertisers reconcile cloaked first party subdomains? It requires fingerprinting, or the first party to tell the real 3rd party (cloaked as a first party) things like email or real name, that can be cross referenced, no?

Yes, that is generally how they resolve it. Apple has started to reduce the effectiveness of CNAME cloaking.

The goal is that advertisers will eventually be far better off working with a system like Private Click Measurement (in Safari betas now and set to be in next releases) than insecure things like CNAME cloaking.
