That's not accurate. Brave offered affiliate link options to users who were searching for particular terms (screenshot: https://brave.com/wp-content/uploads/2020/06/image3.png). These were presented to users as a way of optionally supporting Brave development. Our mistake was matching fully-qualified URLs too (screenshot: https://brave.com/wp-content/uploads/2020/06/image2-1.png). When we were made aware of this, we corrected the issue promptly. No revenue was made from this feature either. No user data was involved. No privacy or security was compromised. This was nothing more than traffic attribution as a means of optionally supporting an open-source, free-to-use browser.

Compare this with traffic attribution in other browsers: open Firefox and begin typing a search query. If you monitor your network activity, you'll find that your keystrokes are not only sent to Google behind the scenes, but those requests also contain an identifier so that Firefox gets paid for sending you and your queries to Google. Brave users were shown the affiliate options before any network activity. Read more at https://brave.com/popular-browsers-first-run/.
As for the question of privacy, Brave was compared to Chrome, Firefox, and more in a review by Trinity College in Dublin, and they found that Brave exists uniquely in its own category as the "most private" browser tested.
