writes "After strong criticism last year, Github has finally accepted the view that public repositories with no open source license are a bad thing. Self-described as the "world's largest open source community," a significant number of GitHub projects come with no rights whatsoever for you to use their code in an open source project.
But from now on, creators of new repositories will have to pick from a small selection of OSI-approved licenses or explicitly opt for "no license". In Github's words, "please note that opting out of open source licenses doesn't mean you're opting out of copyright law.""Link to Original Source
