I don’t, I’ve never used Brave.
From https://brave.com/brave-rewards/
Brave Ads do not replace current web page ads. By default, Brave blocks privacy-invading web ads and trackers that are embedded in page content. Joining Brave Rewards and viewing Brave Ads does not affect your current blocking settings for each website you visit. The ads you see as part of Brave Rewards are shown separately from your browsing experience and are not the same as the invasive, performance-sapping ads embedded in websites.
But I can already block ads with uMatrix and other ad blockers. So why do I need another browser that does essentially the same, but adds more complexity to the mix, potentially more browser bloat? So instead of funneling ad spend to google, it’s funneled to Brave - but that doesn’t really make a difference to me as a consumer. I can donate or buy products of creators I want to support w/o dealing in BAT.
