This isn't just a non-profit holding company for tax purposes - the whole thing is structured with the intent of giving the non-profit complete control over the for-profit to help achieve the non-profit's charter.
The board being full of typical business people would likely be counterproductive to the goal of staying focused on the non-profit charter vs. general commercial business interests.
I don't know enough about most of the board to have any sort of real judgment about their ability, but there's a lot of comments here that are judging board members based on very different criteria than what they were actually brought in for.
