Why Did Microsoft and Sun Support SCO?
In Sun's case it was, as we knew, to try to slow down Linux, but also to use SCO's intellectual property rights to Unix.Back in the beginning of SCOs all-out assault on Linux and IBM, the Unix company received a much-needed financial boost to its lawsuit plans with two major contracts. These deals with Microsoft and Sun brought SCO $26.5 million. This money, in turn, fueled SCOs lawsuits. At the time, many critics of SCO wondered what in the world Sun and Microsoft could have been buying from SCO. Most people thought the answer was that they were buying an attack on a rival company, IBM, and a rival operating system, Linux.
Now, as a byproduct of SCO v. Novellthe case over who really owns Unixs IP (intellectual property)and thanks to Groklaw, we now know what Sun was buying from SCO (PDF download). In part, it does seem to be an attack on Linux. But that wasnt all.
