I disagree as even a monopoly has its limits. Especially in the form of technology. You used Microsoft as an example. Certainly they had a monopoly for a time, but now it's clear that Apple is the new king of the mountain due to technological advances and the demand for them. If you think in hindsight, if you had the monopoly on anything such as bell bottom jeans, steam engines, or anything really. Eventually, the monopoly is rendered worthless because the product is no longer wanted or needed, or you flood the market to the point where demand dwindles.
