According to the specs, the requests are made without user agent headers, leaving only IP address. Targeting ads based on IP address isn't particularly valuable to ad networks if they can't correlate it with anything other than the sandboxed cohort data.
If you give me a demographic group (age, sex, income, etc) of a thousand people, and give me the IP address I can uniquely identify the individual within that group using outside data sources like Experian.
What insane ramblings is this? Every site will be forced to use an approved CDN? Adding forced MitM to every connection is the opposite of what we should be trying to implement.
