But they have done so using libgit2, which is licensed under GPLv2 and developed by GitHub. Microsoft are not only shipping it; they are also contributing to the project. Remember, the GPL was what made Steve Ballmer call Linux a "cancer" and has been the focus of Microsoft's fear of FOSS for a decade. Has hell frozen over?"
