You can choose: either have your privacy or more convenience.
This principle applies to so many things in modern life. A bunch of my friends use various smart home devices - Google, Amazon, whatever. They say it's super convenient: "Add x to my shopping list" or "What's the weather like tomorrow". I say I'd rather spend 10 seconds doing these things myself than having every single word that is every said inside my house being sent to and recorded on who knows how many servers around the world. You like the convenience of connecting with friends on Facebook, Instagram, Snapchat, etc.? Then you are giving away all your data to these companies to use anyway they want and sell to anyone they want.
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.
I disagree with you here. Even if it doesn't affect me directly, I no longer want to support a browser which advertises itself as having a strong privacy focus, whilst simultaneously mandating KYC for part of their userbase. KYC is completely antithetical to everything they should be standing for.
