The whole premise of this paragraph is wrong. Yes, most big businesses run Microsoft Windows, but most people hate and struggle with it. They run it not because it's the best, because it's not. They run it because monopolistic business practises forced out the competition. If he's trying to argue that Microsoft are misunderstood, that they do deserve respect after all, then maybe respect the hard-nosed business practises which have forced Microsoft products into every nook and cranny despite consistently having a shittier product than the competition.
