Bromite is only for Android, but I guess Android web browsers are missed when mentioning FLoC. Also, from what I see, CalyxOS build of Chromium either has FLoC disabled by default (and it is on version 89, by the way) or I haven't been FLoC'd. Actually, since I disabled third-party cookies, I can't be FLoC'd. And also, it doesn't look like the Calyx Institute mentioned FLoC and whenever they disabled it in their build of Chromium.
