Because not every app you download needs to know all of your information
Possibly because it is not open source and doesn't have anything to offer that the other recommendations do not.
You can view "Brave ads" in exchange for crypto. That is what I meant by replacing ads.
trustworthy
They are recommended on privacy guides: https://www.privacyguides.org/en/search-engines/#brave-search I generally trust privacy guides, although I don't use Brave Search.
CEO
Their CEO is anti-vax and homophobic. Brave Browser (not search) has had some controversy around including crypto, replacing ads with their own, and having had inserted affiliate links into the URL bar in the past.

There may also be some benefit to using the extension for your password manager, as it may help you identify phishing links and prevent you from filling in your password on fake or scam sites. I strongly recommend Bitwarden as a password manager.
Installing extensions is unlikely to help you defend against fingerprinting. If you are concerned about fingerprinting, then you should enable resist.fingerprint in the about:config on FireFox, or use either Tor or Mullvad Browser (which you should not install any extensions on).
