Brave as a company being shady isn’t anything new though. Purely from a privacy standpoint, however, there has never been an indication they have violated users’ trust in that regard. The latest furore you linked is questionable, but nothing to do with privacy.
Still, I personally have very limited trust in the company which is why I don’t use their browser and only rarely use their search.
It once again pains me slightly to be defending this company, as I really do not want people to ignore their questionable business practices when evaluating their trust in them. With that said though, it is important to present correct facts:
Using the EDDM service provided by the USPS that allows blanket mailing of every house within an entire ZIP code does not constitute a “customer list leak.” This is just targeted spam mailing to a ZIP location; Brave don’t even know who they’re sending the mail to. Most likely aren’t Brave users and probably don’t even know about the company, which is the entire point of sending them spam mail I guess.
Your message makes it sound like Brave acquired and printed the names and addresses of Brave customers to send them mail, constituting a leak of their customer list. They didn’t.
