At stake here is far more than SCO's existence. It is the front line in a battle between two diametrically opposed ideologies. In the red corner we have open source - the idea that software should be freely available and that it is best developed by a community of interested individuals who incrementally add to it for the common good. In the blue corner we have traditional software companies, of which Microsoft is the exemplar. Their philosophy is that software should be created for profit and owned by private companies, who get their revenues from initial sales, upgrades, and services of various sorts.
