I think an important question with the FLOC stuff is sort of brushed aside. So, you have millions of users, and you make it "k-anonymous", or "anonymous if you squint real good". Is it really possible to find k such that privacy is meaningfully preserved, given the heaps of other information you have? Say I belong to some cohort, and you know my IP address. I think this would be enough to fingerprint me reliably, never mind OS version, browser, plugins, etc.
