Protecting the monopoly
This commentary is right on. For the past 15 years--essentially since the bundling of Windows 95 with DOS 7 (or 10 or whatever)--Microsoft's entire business model has been protecting the Windows/Office monopoly. Protecting a monopoly doesn't inspire or encourage innovation.
Indeed, conservatism assures certain and quick death in the tech industry. If Apple's IBM's, intel's and Google's models are any indication, change is the only path to strength and growth. Microsoft is spending way too much time thinking about abusing new models to extend its monopoly instead of dreaming of new ways of exploiting the new models.
