Yes, the Wrights were poor businessmen. That does not take away from their great success at flight. They still managed to become wealthy.

They needed to test and go further. They left 99% of the potential wealth on the table due to their greed. A proper management strategy would have led to progress and volume production. Instead the Wright patants were so difficult or expensive to licence that they were allowed to lapse = bad failure mode...
