One of the first things I do on a new phone is I uninstall the Google app (ADB) but I do it only for my user (me). So it is unavailable to me, and it doesn’t run in the background. I think I could uninstall it completely and nothing would break. Some things rely on it - the podcast app did (a while ago), google translate (when I try to translate a photo).
However, I am actively eliminating google from my life. No Drive, no Photos, Gmail is what I use when I want to subscribe to some crappy service (I moved to Tutanota, and I’m a paid user). I don’t use Google search (I do a mix of DuckSuckGo and Brave search - which both use Bing ¯_(ツ)_/¯ ; I’m thinking of moving to one of paid search providers).
