License issues
"The experience may have made some consider alternatives that do not need Microsoft's licensing infrastructure to tell them what they have bought"
It's been 20 years since I stopped using Windows on my personal machines, and licensing was one of the reasons why. Not the biggest reason (that was that a Windows malfunction caused me major data loss), but it certainly was a big factor.
I have never regretted that decision, and the decisions Microsoft has made about Windows since them continues to make me ecstatic about dropping it.
