This mail is from 3 years after Gates stepped down as CEO. I think you are trying to use this to reaffirm your personal beliefs about MSFT, rather than use this form your beliefs about the company. You seem to think that because MSFT made Gates a ton of money, the company should be perfect. The fact that you find it bizarre for a founder to be actively involved in his company's products and working to highlight areas needing improvement is, frankley, bizarre.
