Hank Scorpio writes "Well, SCO is at it again. I just received an email from their Developer Partner Program stating that not only are they suspending all future sales of their own Linux product (due to the alleged intellectual property violations), but they are also beginning to send out this letter to all existing commercial users of Linux, informing them that they may be liable for using Linux, a supposed infringing product. They mentioned that they will begin using tactics like those of the RIAA in taking action against end-users of Linux. This seems like it will be about as successful as the whole GIF ordeal a few years back. Where is UNISYS today? Is SCO litigating itself into irrelevance?"
