Tell me, looking at Microsoft at its height, and then its decline from the monopoly position of 95% of the market, what was responsible for the fall? Mobile, that was later on: but first was its naive reaction to the Internet, opening up the monopoly desktop in a totally unprotected and insecure way. When you could see the hard drives of your entire neighborhood, because everybody turned on file sharing with their own home network in mind. When raw sockets were allowed without restrictions, and the firewall was off by default -- Microsoft engineers "innovated" themselves into the world of the status of old Windows machines being good for nothing but the propagation of bot armies. So of course, Bill doesn't seem to understand security yet.
