literally,i hate google's dominance on the internet.the internet should never be used for one's own benefit,it should be for the benefit of alI.i remember how chrome was my favourite browser when i was younger.gave it up as soon as i came to know of its dark side.
Believe me,all of my family members,including cousins and friends use chrome as their daily browser,i am very sure none of them knows anything about this FLoC.well they wont be bothered even if they come to know about it,the just don't really care anything about it.
i know chromium based browsers are very safe(exept google) but i no longer use any such browser,i mainly use Firefox and use Tor as a side by side experience.
