Was forever turned off Brave when they sent me direct mail advertisements (for a privacy focused browser lol). They bought my info from some list and spammed me with postcard ads.
I've never gotten an unsolicited e-mail ad from DDG. And for every half-serious company which does send unsolicited e-mail ads, at least I know I'm the one who gave them my e-mail address. If people are getting e-mail ads from Brave without ever having disclosed their e-mail address to Brave, that's seriously concerning.
