Let me make it really simple: Anything that happens in a company is always, always management's fault. The investors hire the management ream to turn a pile of money into a bigger pile of money, and if management fails, it is management's fault, because it can do whatever it needs to do (within the law) to make that happen. That they failed to hire, train, motivate, fire, promote, follow the law, develop the right products, market them well, ensure reliability, ensure business sustainability, ensure reinvestment in research and development, and ultimately satisfy investor, is their fault, and they further demonstrate their failure by not taking responsibility for their own failure and blaming others.
