If you are downloading fonts from Google, Google harvests your IP and likely the referring site from the request. Even if your browser doesn't sent the referrer, many sites have a unique enough font-fingerprint that Google can figure out where you are.

Would this bypass most Google Font tracking? An extension that makes Google Font requests on behalf of the requesting site and caches the response indefinitely and for all sites, somewhat like LocalCDN/Decentraleyes, but on demand.

That would prevent Google from getting every request.

FWIW, I'm not sure how much of an issue this even is. My comment was a hypothetical. Sadly the way Google/ Facebook/ etc operate, I just assume that whatever I think of, they've already done it plus 1000s of other things which would never occur to me.
