The explanation favored by conspiracy theorists is that Microsoft is paying a lot of money to SCO or SCO executives to illustrate one of its more effective anti-Linux points, that Linux users may be vulnerable to intellectual property liability.Care to re-think that?
While this explanation makes logical sense, Microsoft would have to be a whole lot more desperate than I think they are to take the risk of exposure. The basic rule here is, "Don't attribute to malice what can be adequately explained by stupidity", and there seems to be enough stupidity at SCO to choke a buffalo.
At a mimimum, it looks like Mocrosoft is giving SCO the opportunity to say, "See? People are still paying for licenses. So our Intellectual property must actually be worth something. Microsoft wouldn't just give us the money for no consideration, would they?"
