"I blocked your source of revenue, now I'm holding some money which you can either sign up to receive a fraction of, or don't and you won't get any" doesn't sound like "consent" to me.
Setting aside the rewards program, people can and will use ad-blockers. Even if those were illegal for some reason, there are lists available (such as hosts, https://github.com/StevenBlack/hosts) where you can make known tracking/advertising/etc hostnames non-routable
Are you saying that site owners should feel violated by folks installing ad-blockers (or using host files)?
No one believes that ad blockers are good for content creators.
Brave, however, positions itself as being good for creators with its rewards program. A user may be forgiven for thinking that this is actually better for creators: "Earn rewards and give back to your favorite Creators. Support your favorite sites with micropayments."
If Brave takes away revenue from the creators, and offers them a fraction of that revenue back, that's one thing. BUT you can't turn around and say that a creator accepting that fraction is "consent" to the whole program.
