Surely to goodness you have a better argument than this.
I don't think you have a clue who is using Linux and for what. Or what you might find runs on Linux today.
But I have to say, you can stir the pot. I liked that you brought up ... lol.. I got ahead of myself.. and didn't post something..

I'll just handle it here.. Yea.. Linus was just a student. Well, it was a Masters Thesis.. that was the problem, no doctorate.
Frankly, I am a fan of the Mach kernel and one of the operating systems based on it.. but Windows had to be a clone of that work because Dr. Rashid, who didn't write the Mach kernel by himself by any stretch of the imagination.. had to leave that technology at CMU.
Still, I am lost about what this has to do with System security. I am happy to concede that some brilliant people teach at Carnege Mellon and for that Matter, I will concede MIT, Berkeley (arrff) and the Colorado School of Mines. :)
