All fine and dandy when it is some curious silicon valley engineer playing with new tech at home, but 'selling' that to people at danger that depends on that tech for safety is huge red flag.
Avoid brave browser like the plage. Specially do not contribute your opensource-time to them, but to the projects they use (not chromium though)
Brave is interesting, and I do play with it. I utterly distrust it, though, and do nothing important with it.
having brave control which ads you see, will lead to the same awful situation when adBlockPlus was stolen for profit: any company could pay to be whitelisted.
Contribute to uBlock Origin [0]. uBlock was also stolen for profit [1] and takes money to whitelist ads.
The vast majority of users do not need tor for personal safety, therefore avoiding brave because of this issue is a non-sequitur for most people. Ublock origin is great, but brave is one of the only solutions that is giving a legitimate attempt at solving the root issues in a pragmatic manner. Everything else (including ublock origin, as good as it is) is just cat and mouse.
