instead of clarifying what definition you are using
and you accuse other people of not learning?
Excuse me for thinking, after I already walked you through this an entire year ago, that you had it straight.
The legal definition is not wrong either, it all depends what you are talking about.
In what universe are you explaining this to me? Considering there's obviously stores besides Steam, there's no reason to infer someone must mean the rigid absolute dictionary definition of monopoly - especially after they repeatedly specify that's not what they fucking mean.
If someone scoffing 'finally you get it' makes you stop getting it, then you did not get it.
Meanwhile.
Back at the point:
Steam is a monopoly. They are the one store that matters, on PC, and being excluded can ruin your game. Either you comprehend this, and accept that that's what the word means when people talk about real markets, or you just plain don't. If it's "distinction without a difference" then why did you spend all this fucking time bickering about the distinction? I'm not the one making it. I'm here telling you, yet again, that the cartoon absolute and a simple supermajority are both forms of monopoly.
Having that power is a concern even if it's not intrinsically an abuse.
