Anything to do with Brave is yikes, and any step towards "opt out" advertising is yikes. Firefox went from "no bullshit" to "one opt out setting" to "30 opt out settings". There's always a first step. The only real reason to use Waterfox over Firefox in the first place is because you don't want to have to find and whack all the opt-outs - Firefox with the right config offers every advantage WF does.
