Can you tell me why Microsoft is NOT a monopoly?

Answer 1

Well , Microsoft brings uniform usability to operation systems, and that drives efficiency for the marketplace. Monopolies tend to be mix bag at times, and the invisible hand will naturally collect resources for its most efficient use. Yet, invisible hand can create market failure in certain sectors of the economy.
Apple, Linux provide alternative operating systems to use besides Microsoft.
Is Microsoft anti competitive? It depends on where Microsoft is competing in the market. For example, the xbox competes with PS3 and Wii no monopoly in video game market. Sometimes, bundling of software Microsoft does at times will create uncompetitive situations. Still, you got to balance efficiency and economy of scale. My opinion is Monopolies sometimes makes the economy more efficient, and if it does not stifle innovation the government should stay out market.
If Microsoft creates a situation where other vendors are prohibited from getting Microsoft licensing and rescriting consumer choice then the government possibly should step in. Its balancing act because sometimes monopolies are good, but most times monopolies stifle innovation, and reduce choices in the market its discretion that needed.
