I'm sure there are plenty of organizations that would love to move away from Microsoft, but its just reality that they can't. They are too invested in it. It would take too much money, too much time and too much political will to make a change. It's not their fault, its not even Microsoft's doing, other than being in the right place (on commodity PCs) at the right time (the '90s.) It's just the way it is.
