As far as I understand it, the business case for not open sourcing Windows is loosing merit. Linux is a very advanced operating system, in many ways surpassing current Windows versions - technically speaking. The problem for Windows seems to be that it has trouble leaving the desktop and its particular server market. Windows-based mobile devices are struggling, and pricing/enforcing Windows licenses for IoT devices would be a tough problem. Pay for a Windows 10 license for a Raspberry Pi? I don't see that as a mass market either.
