The scenario is something like this:
Random person: recieves a physical mail right after installing Brave.
Brave: we are so so private and don't ever sell or use your data.
Random person: how did you get my address then right after I literally installed Brave?
Brave: you see, it's very private because we can't see the address or who the mail is going to go to. We just contracted a mailer who sent this marketing newsletter to everyone in their database.
Random person: ...
Brave: maybe you didn't understand but we, the brave company, didn't see who the mail would go to. That's privacy right?
Random person: deletes Brave
The problem here is that a privacy oriented company is accepting and making use of a very non-private method to spread privacy and Brave. Contradictory in it's core.
I still like Brave and what they represent. I am a fan. They do a lot of things right but this was baffling. I don't know how they could allow something like this to pass through the filter...
