I'm going to pass on the browser part owned by the chairman and cofounder of Palantir. I don't trust it for that and other reasons. I don't have the skills or interest to audit and compile every release myself. I don't do it with the browser I do use, but the threat model is different for its maintainers.
Brave’s founder is Brenden Eichman, formerly a long time exec at Mozilla, so it’s at least “complicated”
Splitting up the market more won't do us any good, better support Firefox (even if you somehow prefer Brave) so there can be true competition, if there's just Chrome and 10 tiny others, there will only be Chrome.
