SCO's target is IBM, not Linux. There's a good article about it in one of the Linux magazines (sorry I forget which). The whole thing has very little to do with Linux itself, and a lot to do with SCO's former (fading fast) position as a licensor of *nix code to the OS efforts of Sun, HP, and IBM.

Linux users may happily and completely ignore SCO. The letter is just a minor ploy in SCO's efforts to force IBM to buy them out (as detailed in the article.)
