Just what I was thinking. The article doesn't clearly answer the question of what level of browser cooperation is necessary for FLoC. I use Firefox. When I'm not using Firefox, I'm using Safari. Does this mean FloC won't affect me?
> FLoC is meant to be a new way to make your browser do the profiling that third-party trackers used to do themselves
This seems to hint that avoiding FLoC is just a matter of avoiding Chrome, with no 'arms race' of any sort.
