I think the main point is: you cannot do everything yourself. It is necessary to concentrate on what you do best and get expert help for the rest. MBAs happen to be experts on something (what ever that may be). That is why they can be useful. That is why you may have jobs for them. These business guys are the first to reject funding for your startup, if you DO try to learn everything yourself and not get external knowledge into your company. Well, this makes the post a bit pointless, indeed.
