I'm still sure as ever Microsoft is no friend of free (as in Freedom, not price) software and can't help but shake my head at this latest publicity stunt. I wouldn't trust their software any further than I throw it.
I don't see how that's anything but reasonable unless you take the position that all software ought to be open source regardless the creators wishes.

In particular, if the software or "work" was never made freely available by its lawful owner, it is not open source.
