> There could be cause for legal action against Github over this
I'm sure there isn't. No one has any inherent right to a GitHub account, and their ToS allows them to ban you for pretty much any reason.
I don't quite get why you're talking about "legal angles"; there's nothing here related to the legal system. Yes, it's stupid that GH makes it so easy to give full access of your account to other entities. Yes, it's stupid that they're going to then ban you for what those entities do with that access. But GitHub has no legal or contractual obligation to not ban user accounts for stupid reasons.
