Not sure why this obvious fact is being down-voted. The comments above don't mention that the killer feature of private orgs is the ease of exit, and therefore, the enormous risk of failure. This remains the dominant feature of private orgs, even if we can argue about certain orgs on the margin. For every example of "users are locked into either the Apple or the Android phone platform", I can think of several crappy Google and Apple products which failed and were withdrawn from the market (e.g. Google Wave).

It is much easier to exit from or steer a private org. For example, it is very possible to run a company which caters to 10 percent of a consumer base by providing niche products which may be slightly more expensive. Those 10 percent will simply consume less of some other good. It is very difficult to do an analogous thing at the state level, because we generally don't get individual "ticket books" which we can "spend" on more of one state service vs. another. The democratic model is that you first get 50+ percent support and then your coalition decides how resources are allocated for almost everyone.
