When IBM did this, they were a hardware company. The OS was just something that made their hardware useful to the customer, it wasn't considered valuable on its own. And if third-party vendors made use of it to make more applications and peripherals available, it meant that IBM would sell even *more* computers. So there was little down side to making the OS available.
But Microsoft is a software company. All they have is their software, and if someone else starts selling it, those are sales that Microsoft has lost.
