SCO is targetting companies that are using Linux, according to
this post on news.com.com.com:
SCO Group, a financially struggling company that claims its Unix intellectual property has been illegally incorporated into Linux, has sent letters to about 1,500 of the world's largest corporations warning they could be liable for using Linux.
This is after SCO's attempt to
sue IBM. I guess this is an easier way of making money than, you know, actually developing an operating system that people want to spend money on.
