Proof positive it's mostly cosmetic, deeply problematic issus remain or we'd be able to uninstall Copilot.
Ironically they may have to in order to stay relevant. I'd be surprised if you could find a teenager today that if you asked "would you pay extra for an iphone or android phone that you could use without an apple/google account would you?" that their answer wouldn't be "why would I want that? I'd be cut off from the whole ecosystem!"
“less copilot” is because they can’t charge for it, so the model is crap, so no-one wants it, so they are removing it where it’s useless.
They won’t be the last.
