He's not fighting against closed systems because they are closed. He's not fighting against closed systems in general for any reason. If he was doing this, then you would have a point. He is angry that the status quo of having an actively supported open Windows platform is being threatened. He is fighting against losing that. The new closed system is just the evil actor that he identified. This is a classical case of loss aversion. [1] Tim would be at least equally mad if Microsoft decided to redirect all its efforts from win32 to cow milking. Would you then claim that Tim is a hypocrite for having drunk milk instead of actively boycotting the dairy industry? Yes, you could make the argument that extremely black & white attitude is necessary, and that if you like some open system then thus follows that you need to fight against every closed system. Some people like Richard Stallman do this. However most people, like Tim, belive that a more gray world can exist, and tend to fight when visible threats manifest and otherwise spend their time on other things.
