Microsoft simply realized what current Open Source really is -> free labor. People will willingly work for free in their own free time using their own hardware on projects of other people or corporations. And they are proud to do that! Anyone not taking advantage of that must have brain damage. Original ideas of open source (free as in speech) are long forgotten.
