I can't really see this being good for any publisher or advertiser, you're cutting in two new parties (Brave & the user) and the CPM will tank due to poor targeting. They'd be better off blocking it and hoping it dies off before adoption.
Maybe users will flock to it to earn a few pennies in ad replacement mode? Certainly not for the oppty to pay for ad-free mode.
