I think that is utlimately valid - although I think the other options are all coming with their own problems. You will then have to instead live with the interests of tech corporations (including nonprofits who ultimately need funding) and advertisers collecting your data, whose interests will ultimately not be much less malignant - or small free software projects of a sometimes quite limited scope. The latter, I think, is also a valid niché, but will leave the overall standards of the internet to corporate interests.

Considering how the CEO here acts for Brave, in my opinion, this is not simply about him being an asshole or being politically questionable. To me - everything about him screams "grifter taking advantage of people's legitimate concerns" - and he has a material interest in your data as well. Brave always felt to me like trying to sell and market privacy instead of proving to me, in their fundamentals, that they actually have my interests in mind.

Which is why I, personally, do not really understand choosing Brave above LibreWolf (or Tor Browse, occasionally), if privacy is your #1 priority.
