Mobile devices I firmly ascribe to ineptitude, and can supply some 2nd and 3rd hand details I've read about.

Servers are more complicated. In the mid-90s Windows NT started dropping in quality, and the much older decision to have mandatory file locking resulted in situations where creating a server with a major MS server application could require ~ 20 reboots. And many more bug and security fixes require reboots than they do on UNIX(TM) based/inspired platforms.

Then one could argue ineptitude in marketing when Microsoft didn't cut deals that could have made their software competitive for mass installations. I really wonder about that, because so many of these need source, but it's "a path not traveled", except internally with Azure.
