DuckDuckGo even created a Chrome extension to block it.\nEven though individual user information is obstructed, Google still shares cohort information by default. Brave argues that this violates a basic principle of privacy: “don’t tell others things you know about me without my permission.”\nIt is not clear whether other websites can use the cohort IDs alongside their first-party data to identify users, a process referred to as “fingerprinting”.\nAnother fear is that algorithmic generation of cohorts might result in undesirable identification and targeting of vulnerable groups.\nObservers also worry that we might be facing a pernicious effect of third party data regulation: the advertising power concentrates in the hands of Google and Apple. Indeed, these companies control a large share of first-party data thanks to their browsers and operating systems.\nA telling sign of the ambivalence of Google’s approach is that they are not testing FLoC in the EU and the UK for fear that it might be illegal.",
