I don’t really agree that Brave should not be used because of a toxic fanbase.
I think the best reason not to use Brave is that they are a marketing/advertising company that claims to give their users privacy. Advertising companies will always have an incentive to invade privacy as it increase add revenues. Brave is just copying Google’s business model with extra steps.
It looks like r/roms has also decided to use Lemmy as a fallback
