I don't really see how a browser that blocks ads is any different from an extension that blocks ads.
Yes, but so does uBlock Origin, Adblock Plus, etc.

Why would they need permission from Google to do that? That's completely unrelated to them.
That'd be a copyright violation. But Brave isn't making or selling copies of anything, so I don't see what your point is.
1) It blocks ads, just like a browser extension would
2) It has a set-up a payment content creators can take advantage of.
I fail to see what is wrong with either.
