Was Microsoft a monopoly? Or did they create a new paradigm and when their services were deemed so valuable and important to society that regulators started viewing their platform as a public utility, they decided to call it a monopoly? The government never gave them a chance to lose market share, unfortunately. Microsoft created a ton of value for people, but they were worsening their product by preventing competition on their "platform" (Windows). If it wasn't for the government preventing consumers from starting to choose their competitors, we might have more Linux-based / Apple market share right now. In any case, no one was harmed except for the competitors who wanted to compete with Microsoft on its own platform. Rockefeller's Standard Oil is an example of a natural monopoly that brought down the price of kerosene by over 50% over the course of his reign. There is a such thing as a natural monopoly, but not a natural, malevolent monopoly (except governments, of course, but even they can be overthrown).
