Microsoft is largely irrelevant to computing of late, the only markets they still play in are evaporating with stunning rapidity. Their long history of circling the wagons tighter and tighter works decently as long as there is not a credible alternative, and that strategy has been the entirety of the Microsoft playbook for so long that there is nothing else now. It works, and as the walls grow higher, customer enmity builds while the value of an alternative grows. This cycle repeats as long as there is no alternative. If there is, everything unravels with frightening rapidity.
