> If the browser is supposed to send the information, what are they going to do with those of US who do not use Chrome? What would stop them from implementing FLoC in the cloud for non-Chrome users? Fundamentally, where the data is stored is meaningless. So long as they are pushing everything through this same "FLoC" model, they are claiming they won't be tracking individuals. So on Chrome, FLoC is local—your own browser working against you—for Safari and FireFox, FLoC is cloud based. So long as the web sites in question are running Google Analytics, they still have the software on your system on a huge number of sites.

> for Safari and FireFox, FLoC is cloud based This would require being to identify a user when they are on many different sites (cross-site tracking), which all the major browsers intend to prevent. (Disclosure: I work at Google, speaking only for myself)

  First, you have to understand that Google as a company has lost all credibility in much of the community. There have been too many issues like this one where Google gives you the impression they are turning off tracking... but doesn’t actually stop tracking you. https://www.independent.co.uk/life-style/gadgets-and-tech/news/google-secret-tracking-location-services-disable-privacy-apps-a8068961.html https://www.independent.co.uk/life-style/gadgets-and-tech/ne... There was also the Do not Track setting, which Google ignored. So in my book (and I’m not alone here), anything coming from Google is taken with a huge grain of salt. For some time, there has been a sort of cat and mouse game between advertisers and browser makers. Do you know Google isn’t using fingerprinting to identify us? Or just IP or some other means?

Additionally, I work in client-side ads infra, and I'm pretty sure I would know if Google were fingerprinting users to target ads.
