Combining those would definitely be a problem. https://www.chromium.org/Home/chromium-privacy/privacy-sandb... describes removing/limiting those fingerprinting vectors, including IP.

How would FLoC audience targeting work in non-chrome browsers? DV360 users deliver ads on all browsers, no?

[jefftk]

FLoC is a proposal for a web standard, which other browsers could implement.

Today, in browsers where third party cookies were removed without replacement, companies like Google that aren't willing to fingerprint have pretty limited user targeting capabilities.

Does that mean advertisers using DV360 will have the option to target using known identifiers or FloC? Chrome market share in the US is 50%. FloC covers 50% of the total US market. Advertisers want all the scale. https://www.statista.com/statistics/276738/worldwide-and-us-...

I think users using the search engine, email, maps etc in other browsers is hardly a "limited" amount of data for ad targeting.

Sorry, you're right, advertising on Google's own properties is mostly unaffected by browsers removing support for third-party cookies. I was thinking about AdManager and AdSense; ads shown on publisher sites.
