I thought the point of those ads wasn't that Brave make money but that you accrue those Brave tokens as a representation of your attention and get to send those tokens to publishers of your choice via the browser?
Also, I turned them off as these ads are quite annoying and have a "cheap feel" to them.
Brave does make money off of them - they get 30%, you get 70%, I believe.
And yes, the idea of sending BAT to websites directly was excellent. The website needs to have registered for the BAT wallet though. (Not a big deal, of course)
