Valve does not have a monopoly by any definition of the word, especially the legal definition. They don’t have a majority of the business because they buy out the competition or use their position to drop prices to a level that others can’t compete with. They have a majority of the market because they provide a better service than the competition and have been doing it long enough to have developed a cultural gravity in the same way that Xbox, PlayStation, and Facebook and Twitter have.
