The nice thing about monoculture-style OS is that the enemy needs only one solution to infest or electronically influence many totally different pieces of hardware and platforms.
At no cost I would give a company like Microsoft, or a company form a foreign country with a strong self-centered agenda, access to my defense installations. Because if that foreign country's agenda collides with my own, I would know where the loyalty of my software lies - probably not with me.
But in variations, this is true for defense hardware in general, I suppose.
Remember the new version of Battlestar Galactica, and Commander Adama categorically rejecting to operate computer networks and Ai-automatics aboard his ship? He even had switched off the remote control autopilot for incoming fighters on the landing deck. Right he is. His battlestar was the only one who survived the electronic offensive that ran ahead of the cylon attack.
Learn from the future, guys, learn from the future!
BTW, the Chinese are said to invest heavily into software- and electronic warfare. While India has the world's largest pool of talented informatic experts and students. And Vista raises suspicion by having been developed in cooperation with american intelligence services. To close security holes, they say. If they have programmed in backdoors by which American services can enter Vista-run platforms - of course never would be admitted.
Microsoft, eh?
