You dont see IBM giving away their AIX operating system for free, do you? And this is despite the fact that AIX soleley exists to exploit IBM hardware (it doesnt run on anything else) and therefore, could legitimately be given away, since IBM's objective is to sell hardware.
Wait, wait... you don't see IBM giving away AIX despite the fact that it only runs on their hardware? And this means it, therefore, could legitimately be given away? Why? So someone can say "Boy, this disk sure is shiny. I bet it'll do amazing things when I put it in a machine that can actually run it. Screw it - I'm buying an IBM mainframe!".
Did this post make sense to anyone? Am I an idiot?
