Monopolies aren't necessarily bad. They're usually more efficient due to economies of scale. They can abuse their monopoly, but that's nothing that can't be fixed with a little nationalisation.

The fact that we should buy games on other platforms because steam has a "Monopoly" was the sarcasm. In a vacuum monopolies are bad, but steam is the powerhouse it is because all other options are crap, multiple store faces that you have to log into are actually annoying and not really adding anything to the average consumers life, AND Steam does more for the consumer than we could reasonably expect ANY company this far into our late stage of capitalism would do. Steams current position on the gaming market is incredibly unique and not part of the normal monopolistic paradigm, and as soon as steam enshitifies, it will lose a lot of its position
