However, they do nag you a bit about it. There's an icon for Brave Rewards in the address bar with a "1" badge asking if you'd like to opt-in (Toggle in Settings to hide this icon). It also asks you during setup and then if you skip (no Deny, Disagree, etc.; just skip), it shows a pop-up on the new tab page immediately after asking for the same thing.
Brave's business reminds me of Adblock+. They started all "we are cool, we make the web a better place" (which they did by the way), then they didn't know how to monetize, so they introduced "non invasive ads". Which is still ads, except this time, it's up to them to choose how ads should look like.
It's the first time I read more about Brave, and despite the fact I like that they try with a new model, I think I'll keep using Firefox and the usual add-ons, as I have been doing for years.
