If he can break his code because he is the owner then shouldn't the same reasoning apply for Github suspending the account?. It is their website and their rules. Keep in mind Github owns npm and the author has published a malicious package to npm which has 20 millions of downloads so I'm not surprised.
IMO they are kind of different things. The dispute about the code itself seems to be more of a licensing thing whereas the GitHub itself seems to be a property thing.
