...so what do you use instead?

No, really, what browser can you use where none of the influential developers involved is some kind of asshole and/or ultracapitalist? Chrome? If Chrome is off the table, wouldn't that "infect" all the Chromium-based browsers? Firefox is out for the same reasons Brave is, I guess, due to the same guy.

Where is the line drawn? At what point does any software become okay to use? Linus Torvalds used to be a real cunt, though I've heard his attitude towards us mortals has improved over the last decade or so. Does that mean I can use Linux on Thursdays now?

This purity testing is stupid because you readily use a bunch of random crap where you have no idea how bigoted or not the creators are. It is literally impossible to vet everything. I don't use Brave, but it has nothing to do with this random C-level asshole. Being some kind of asshole is a requirement for a C-level position anyway, so let's not pretend like Mitchell Baker is a saint or that Sundar Pichai walks on water. It's all the same mush.

In the end, I care if the software is good. Firefox serves my needs just fine, so that's what I use most of the time. Not as a political stance, but because I'm comfortable with the software. I bet at least 18 people involved secretly hate cats. Oh no, that means my purity is compromised. Oooof Nooooof!
