So will Miscrosoft have to pay for a SCO License?

Since they're using Linux?

They were actually one of the first companies to pay SCO's extortion, ostensibly, one would assume, because of the Unix code found in many MS products, but, more likely, according to conspiracists, to pay off SCO for ruining their company to create more Linux FUD.

Oh, well there you go . . . not so funny then.
