Chrome based browsers can share your ad preferences, bookmarks, cookies... it's spyware. You can tweak your chrome settings to reduce the surveillance but you can't reduce it by much if you are logged in with your google account and use google services. Brave is based on chromium which can be a little bit more private than chrome if you know how to tweak it for privacy in the settings menu. No more debating antis if they censor social media like this.
