Many chromium browser have built-in adblockers and some of them are on-par with uBO. These are not extensions, so Google can't really do anything about them. Not worried in the slightest.
EDIT: Let's both save our time: "Brave bad, CEO evil, Chromium, cryptoooo, etc... ". I don't care. Mozilla isn't less shitty at all and Firefox is mediocre (source: have been a FF user/advocate from 2002 to 2021).
You're not interested in debating because you're scared of being shown how wrong you are. Don't say anything if you don't wish to debate anyone, it's an open forum, in case you forgot. You don't dictate the rules.
