How?
You will ask me to use duckduckgo.com for my search engine? I have no problem to use tor browser in fact I do use firefox with tor connection but asking me to use duckduckgo.com is boring.
I do not like it. The annoying part is that everytime when you are going to search for anything you are starting it from the scratch since the browser does not know anything about your interest, preference. I know that's the goal but these days we are so much addicted with technology that if you ask someone to add 122 + 123 (just picked some random number) then they will look for a calculator.
You can choose: either have your privacy or more convenience.
If you let Google track your location 24/7, they will give you cool custom alerts, suggestions, timelines, custom searches, etc... But they need to keep tracking you for that. If you don't mind, sure. But some people prefer to do a hard search on DuckDuckGo than having Google know what you like, think and even the porn you watch. What else do they even do with that data?
About Brave, as long as they don't track me, sell my data or some shady stuff like this, I don't care about what KYC they implement *for publishers only*; If they need to do that in the eyes of the law/government, they will obviously do.
