Quickest answer I can give you is to search this Community for ‘brave browser’, where you’ll find links confirming that:
It’s owned by a scumbag
It’s selling copyrighted data that isn’t its to sell
It’s crypto offering is a bad joke
It has been caught installing software without user knowledge or permission
It got caught inserting affiliate links
Basically, trust that Brave Browser can be a good product and trust that the company are responsible is pretty much dead. Every time they try and sneak another thing past their users and (inevitably) get caught, they of course apologise and promise never to do it again. Then they do it again.
