There is a whole field (now relatively mainstream) of differential privacy, concerned with answering questions such as "can I be correlated and de-anonymized across queries" (query might be "what's your current cohort id?").
Is FLoC not built on sound principles of differential privacy? That would be a big shame on Google.
EDIT: Huge shame on Google! From their FLoC whitepaper: "We want to emphasize that, even though differential privacy is now the de facto privacy notion in industry and academia, we decided against using it as our privacy measure for building audiences."
