‘Some people insist it’s not a monopoly’ is restating the problem.
Any discussion of Steam’s overwhelming market share requires the question ‘why does overwhelming market share matter?’ and the answer is ‘because that’s a monopoly.’ We could dance around the word itself, and just describe an elephant, but that only delays when people with misconceptions hear the word for this animal and go ‘nuh-uh.’
That delay would be worse - because it allows for people who acknowledge all the reasons Steam is a monopoly, and all the reasons that monopoly is a systemic risk, but will still insist with kneejerk certainty that Steam doesn’t count. It’s some other distinct thing, despite the absence of difference. That denialism is a lot harder to deal with than just telling people:
Real markets never have absolute monopolies.
When people say monopoly, they mean the legal definition.
Dictionaries which do not reflect that use are incomplete.
It’s cute how the word is interchangeable with the situation only when it suits your bickering.
When people think the word can only mean the cartoon absolute, weee shooould fiiix thaaat. I sure the fuck have not been arguing the word doesn’t matter - rather the opposite, at length. You just keep insisting risks don’t matter until they become actionable problems.
We must recognize this monopoly, because of the potential problems it can cause, even if those problems are at present only potential.
We really fucking ought to use the word specifically for this situation, because people already fucking know why monopolies are bad, even if they’re confused about what monopolies are.
