Based on the license terms, it seems that they are trying to intentionally taint the linux code. If they put out this code under this license, and then find some of the patents in Linux later on, then SCO Part 2 will have a leg to stand on.
I was thinking the same thing people who are not programmers don't seem to realize that about every data structure and algorithm out there has been tried. Some kid in college or a cubicle monkey learning a new language might use the MS code as a tool in that quest. Later down the line when they are coding something they might apply what they learn and unknowingly break a patent.
Poison pill aimed at the Mono project. Stay away from it.
Yes, they are more than willing to do what they can to taint Linux - it is their poison pill should they lose their Office monopoly, which is their main source of income.
