The original claim was that computer platforms tends toward monopolies. The existence of consoles is an interesting data point but it isn't a counterargument to this.

The user-developer loop (1) is part of the reason, and API / data lock-in (2) is another part of it.

Just like in the first case, causation in the second case goes both ways. Corporations (and not just corporations) buy Word because there is Word data and there are Word users out there.

"Corporate purchasing" doesn't explain very much to me and isn't the salient difference between consoles and phone OSes or desktop OSes. Corporations bought Windows because of the more fundamental factors that I'm pointing out.
