Actually, what I mean by that is rather the difference in power between the guys doing the coding, and the guys making the business decisions.

Both tend to enforce that divide, but for very different reasons; the coders for cliquish reasons as I described, and the business guys like Apple for the reasons in the original link.

The coders can't really enforce anything. We have opinions and fall in groupthink indeed. But the mere fact that there are different tools is obviously caused by the people and organizations that create them.
