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.
This is quite normal for an enterprise product though, and I agree on the deanonymization part. But I would not expect anonymity on such a platform anyway because GitHub is very often used in the place of a resume or a CV.
Simply put, you are not the kind of user they want. Happily there are alternatives. I started backing up private repos to SourceHut.
I'm on the same boat. For now I don't mind because I use a few other Git hosting services point as a backup while still using GitHub. I'd like to move to another service though, it'll be a conundrum.
