It is true!!. A dispute that had no basis. If they had asked reasonable royalties it would have been OK, but they refused to licence many makers - yet they failed to make their own planes in volume for related bad business reasons. Did you read where the early USAF on that era was forced to buy French a dn British planes due to the bad management by the Wrights

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...
