Not a github user (*lab), also not a lawyer, so please excuse my ignorance. As this boils down to legal arguments, are there any clauses (maybe disputed) in the ToS allowing github/MS usage of public repos for such purpose? Would it even be legally possible to override a software license as a repo provider like "by using this service, you agree to..."?
