So far, I believe I’ve only seen ads in the form of desktop push notifications appearing outside the Brave browser. This, to me, is the worst and most annoying kind of ad. I don’t think I’d mind ads that show inside a web page in the browser if they’re discrete, but I certainly don’t want to be disturbed by ads in the form of push notifications.
Under Brave Rewards, in the ads section, I would welcome a list of the kinds of ads that Brave Rewards supports and give users the possibility to opt-in or opt-out of each type of ad.
