> I don't get this argument. Windows and Mac OS X are also more popular; does this mean we shouldn't use any other OS because all of the cool games are almost exclusively developed on Windows?
Seems like that isn't the same situation. Rather the author should have asked " Windows and Mac OS X are also more popular; does this mean we shouldn't restrict developers to using a non-Windows, non-OS X system?" and the answer is quite simply "no, you shouldn't". Choosing a VCS means every needs to use that VCS. The same is not [necessarily] true for which operating systems can be used for development.
