I am in a situation like you. Doc made me a lot of money, and cost me a lot. It's easy to kick him when he's down. His blemishes are so much more noticeable. And there is no question that his arrogance has him (and us) in hot water at the moment. But consider the fact that there is nothing wrong with the company. Ultimately its success will be measured by how its customers are treated, Doc or no Doc. In his favor, and what Wall Street forgets so quickly, is that he has built a company that dominates its markets, has huge margins and is ahead of the pack in seeing where the market in which it operates is headed.
Can he get the capital at fair prices to accomplish his goals? Maybe. Maybe not. If he can't, don't be surprised if he says "life's too short" (you may have heard him say that before), and takes it private.
