That's a good point, but it's also a "hiding solution" of a completely different magnitude. It would probably be cheaper for most such organizations to just pay off SCO instead of abandoning Linux in favor of another OS, which they presumably would have to buy. So that solution for hiding the evidence is probably not economically practical.
And I'm trying hard to ignore your "Tell me another good joke" type responses in the interests of maintaining a civil debate.
FreeBSD is another possibility.
