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.
Pretending there's a difference doesn't avoid the confusion... it is the confusion.
