Yeah I suspect this is part of their overall revenue model.
Honest question: Why do you suspect that? (I work at Brave. We're all very, very nerdy here. It'd be helpful to understand why a fellow nerd suspects we're up to no good.)
If the person doesn't want to make money from their fans, that's their choice and it's not cool to possibly mislead fans into thinking the person is taking their money.
It's a pain for people to have to constantly monitor all the random sites collecting money "for them". New services are popping up all the time, how are people supposed to keep track? No, Brave is not going to be able to find the correct way of contacting everyone.
If your service is great, why not make it opt-in and advertise it? Patreon succeeds because people want to sign up and make money from it when they're ready to do that. I believe you're all trying to do their right thing and not take anybody's money fraudulently but this isn't the right thing.
