MS v LNX
From Robert X. Cringely's "Why Don't You and He Fight?" ("The folks at the SCO Group are acting strangely, says Bob, and Microsoft may be the source of the strangeness."):
Microsoft is playing the spoiler here, trying to sow fear, uncertainty, and doubt in the community of Linux vendors and users. Microsoft can't beat Linux on price, they can't beat Linux on quality, they generally don't even beat Linux on support, so the cheapest way to compete is to be sneaky. It would not surprise me at all to learn that Microsoft is bankrolling SCO's legal case. I am not saying they are doing so, just that it would not surprise me.
