Brave themselves said that such tests are useless (which they are because they only compare you to other users of the site which are heavily skewed and because they only register a subset of values since they don't show how commercial trackers act nor do they want to again Brave says this themselves )
As for the fingerprinting issues. Type into Braves issue tracker fingerprinting and look on the dates that they have been open since. The worst fingerprinting offenders (fonts, client dimensions) have been open since years (and the original issues got deleted so those are already newer than the original ones).
And no the Palantir case is not schizo. Palantir themselves say we provide US government with user data to analyze threats. This is a fact the company acknowledges themselves. Brave got major funding from Palantir (which they disclosed like they have to). If you think that does not put them in a situation to sell their user data you should be trusting Google who says they don't sell user data if you opt out. Google at least is under regulatory scrunjty worldwide. Brave is too small and irrelevant to be brought up by lawmakers their only users are tech illiterate script kiddies who fall for marketing schemes.
Funny thing is Brave themselves say buried down in their wiki to use Tor browser over Brave if"your personal safety depends on it" because they know very well how easy it is to deanonymize Brave.
