I would hope that they wouldn't have all of them everywhere. That's just plain overkill. Plus, they're not really appealing at this point. I'm not sure if they're supposed to follow you around on the internet and then present you with different products and services, but I'm not interested in anything they're trying to sell me.
The Brave Browser automatically blocks ads, so that's cool, and at some point, you're supposed to be able to earn BAT if you choose to actually see ads and click on them. So far, that's not happening, but I do like the Browser part.

Yeah, that was the first thing I noticed that broke on me because of the banner ad across the top. I wasn't very happy. :)
