The argument of Sony and Microsoft not allowing 3rd party stores on their consoles is an open and shut case. There's no discussion needed there. Everyone already acknowledges that's the case. So the conversion moved on to a more interesting topic: whether Sony and Microsoft have a duopoly. The GP claimed they did and I was making the point that they don't.

The confusion here is you're reading my comment thinking we're discussing a different topic. So it's not me who missed the point :)
