Summary: Norway's adoption of GNU/Linux was noted here last year; it has since then increased a lot; if one counts mobile devices as well, not to mention ChromeOS, it's looking far worse for Microsoft and good for "Linux" as even in rich countries we see that it's not about price but about control/freedom
In short, it's not too clear what Microsoft has just done except dumping GitHub - i.e. mostly a Web site that loses a ton of money (it always lost money) - into some mysterious new bucket
