But, what about the people who don't use Chrome? I would hope that most people who know what EFF is already don't. Firefox will surely come with a way to disable it, or you'll configure it to always send "my little pony" or something like this.
In the end, this seems to really be about Google (with a browser) competing against Facebook and other ad providers (who don't have a browser).
> 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.
