At some point Google decided that it’s a good idea to show you your userpic all the time in the toolbar, which can’t be disabled. Then Edge did the same, macOS Preferences followed, and now Windows Settings are doing the same.
My question is: WHY? Why do I need to be reminded that me is me all the time? Avatars in web are needed because web is by definition “someone else’s place”. It’s good to have your own presence on the page. It also signs out all the time, so it’s also functional.
But in the OS I log in once (and avatar on login screen are fine) and then the whole computer is mine. I don’t need to be reminded about that! Nobody else uses it! I never log in/log out, so it serves no function.
Also, I couldn’t care less under which account am I logged into Chrome (not Google in general, but Chrome specifically). Sorry, Google. I think nobody really does.
