Third-party tracking cookies have not been a problem in my browser (Firefox) for quite a while now, since they get blocked by default. Firefox also recently introduced Total Cookie Protection, which is a feature isolating cookies by the origin on which they were created on. (https://www.theregister.com/2021/02/24/firefox_cookies_86/)

So the argument for FLoC is moot because this is actually a false dilemma. We shouldn't be acting as if it is a choice between either third-party cookie or FLoC. Rather, we should reject both.

Aside: In some ways, FLoC is worse than third-party cookies since the latter are not under central control and do not provide a way of automatically grouping an entire browser user population into similarity groups based on past browser history.
