I will never use Brave after the debacle where they injected content into sites downloaded over HTTPS to pretend people were promoting their crypto token and adding a "donate" button on the page.
It helps if you're doing mundane things and want to help people who need to mix their sensitive traffic with it.
More people "legitimately" using Tor makes it less likely to have its exit nodes outright blocked, as well, and assuming all traffic from them is malicious.
