Looks like you need a geography lesson too.
From the article: "In this paper we discuss the design and implementation of Fellowship, a 300+ CPU, general use computing cluster based on FreeBSD."
So BSD does have multiprocessing ability. With this in mind I say again:
So your issue is not (1) The license itself because BSD is far more permissive than Linux, or (2) Technical Abilities because BSD can do anything Linux can do. Your issue is how other people use the software. I'm not saying this to pick a fight I'm just trying to get at the root of why its ok for BSD to give away UNIX technology (which is far closer to true UNIX than Linux is) to anyone with no restriction but its not ok for Linux to do it with restrictions.
