The irony here is that the real, original SCO (or rather, the Santa Cruz Operation) sold their IP and Unix business to a company called Caldera -- who had already successfully sued Microsoft over the DR-DOS/Windows 95 lawsuit started back in the day by Digital Research, whose IP rights they'd purchased. Caldera were an also-ran Linux distributor who ran out of capital in the 1996-98 time frame (I forget precisely when) and pivoted into litigation. The Microsoft lawsuit victory gave them the money to buy the SCO IP and go after IBM, which turned out to be a Really Bad Idea because IBM's legal department back then made Microsoft's look like a teddy bear. The original SCO changed their name (Tarantella? I think?) and were eventually absorbed by what was left of Borland. Irony: I worked at (original, non-litigious, UNIX-developing) SCO circa 1991-95; if SCO's execs had their eye on the ball they could have rolled out their own Linux distro with a ton of valuable extras backported from Open Server and cleaned Red Hat's clock. But instead, despite half of the UNIX dev team moonlighting on open source projects, the official line was that Linux was an amateur-hour hobbyist project that nobody would ever pay for.
