Perhaps you heard some false claim we "replace ads" on pages -- this is usually asserted without skepticism. We've never done this, we talked about doing it again only with both user and publisher opt-in, via private matching and anonymous confirmation so no remote tracking at all.
Anyway, if you don't like ads on the Web, use Brave. If you want to try Brave Ads to get tokens to give back to your top sites and channels, rather than free-ride, cool. If you'd rather not try Brave Ads but want to give back, you can do that too (you have to sign up with Uphold, though; regulators do not make this easy but it's doable).
How do you justify such a broad-spanning assertion?
All true, and this is why I use Brave. Brave punishes privacy invading ads.
If you opt in to BAT, Brave values attention and gives users control over how the attention value is spent.

Here is an excerpt of the read.me:
It uses a tokenisation approach for quickly reducing the potentially matching rule search space against a URL.
The algorithm is inspired by, and closely follows the algorithm of uBlock Origin and Cliqz.
