I think that maybe the owner assumed he was rich enough and had money for the rest of his life to live however he wanted worry-free. I think it's very important to recognize when you have enough and use the rest of your life to actually enjoy it, as opposed to worrying about legal, technical, payment, security and volatility issues. The stress and workload of running such a huge company takes all the joy out of life. Well, at least that's one man's opinion.
