Don't let the Firefox fanboys cloud your judgement with their constant shilling. Most of the claims in the article have been retracted after Brave responded, and the issue didn't affect users anyway.
Also, Brave is a completely independent search engine now, which is why they have web crawlers like the guy in the article is complaining about. And speaking of a distributed crawler, Brave Browser has an opt-in feature for that where sites you visit will be indexed by Brave Search.
Brave Search is the only real contender to be an actual competitor for Google Search, but these Firefox fanatics have such a hate boner for Brave they just want to see it fail. All of their arguments against Brave really aren't serious and don't affect users at all.
wow I wish we learned this kind of stuff in school
