Of course you are welcome to not use Brave, but who are you to decide whether I think my browser vender deserves my money (or attention-based money) for the services they provide? You literally said "Your browser vendor doesn't deserve a cut of the value of your attention/privacy".

I am not 100% in favor of Brave's monetization strategy, though I'm very glad they are trying something less common. If their overall execution was more to my liking, I would gladly pay them for the service. You have no business presuming to decide for other people what they find worthy of compensation.
