Just read in on /. that Microsoft is releasing an alpha release of a new OS called Singularity under an "open source <...> academic, non-commercial license".

It has just occurred to me that a guy named Linus Torvalds did the same back in 1991, releasing an OS kernel under a "free, strictly non-commercial license". He later got the clue and changed it to GNU GPL.

Apparently Microsoft is 17 years behind; will they get the clue? I doubt it.
