From what I've read on FLoC (not much so I may be wrong), wouldn't having anonymized ad-targeting be a good outcome? Google and websites still get their ad revenue, and we still get ad-supported products. I guess there's always the possibility of a badly-anonymized algorithm leaking data, but other than that it still seems like a step up from that invasion of privacy being a given, no? If I'm misinterpreting the jist of FLoC, let me know.
