Why Does SCO Focus On A Minix-to-Linux Link?

ansak writes "In the latest scoop from Groklaw, Groklaw user talks_to_birds pointed out an error in SCO's version of the famous Levenez Unix Timeline. The important error is the green dotted line which shows Minix to be a derivative of Unix. If this were accepted, and if Linux was shown to be a derivative of Minix, then SCO's lawsuits would be more likely to have merit. As it turned out, even MS called Samizdat unhelpful, but at least now there may be a plausible reason why someone would try to make the link between Minix and Linux in the first place."
