Microsoft is not really a software company.
Microsoft is a gang, kind of like the American Mafia. They don’t shake you down for “protection money” like the Mob does, their racket is shaking you down for licensing fees. They make it so you can’t do business in the IT sector without giving them their cut. They call it “partnering,” but it really means “You don’t do no business ’round here unless Mr. G gets his cut.”
