Personally I most dislike forced deanonymization with 2fa or annoying me with device verification which locked me out of my anonymous account with old expired email (I didn't need it secured and I don't want to prove anything to MS to restore it too). Some people also reported increasing external CI services throttling in favor of Actions, I wouldn't be surprised if they give preferential treatment to Packages too. In the end I don't want power of MS over my code and workflow to grow too much. I know they claim Github is independent but it's not really reassuring.
