If anything, it shows how Mozilla with it's resources are just wasting money, brave was bootstraped with a much smaller team and capital, yet they defended privacy in a way Firefox never could.

I have some familiarity with Brave. They use Chromium (or some components of it?) which is probably more secure from attackers. It has some built-in privacy, but how is it better than Firefox's?
Because it blocks ads and all trackers with no exceptions? The reason is they aren't afraid from Google, in addition to that they launched a fully independent search engine and added new isolation features to chromium, like localhost access and cookie isolation.
