Except in this case it is ok to single out something that is produced by a single company. I am weary about non open source dev tools lately. I was burned pretty badly by MS when the killed managed directx and said - learn XNA. Or all those guys with silverlight experience or the ones that knew flash and become hostage of the Apple/Adobe war. The moment some other entity can kill the technology that you make your living with you are in a trouble. The decision to adopt new MS tech is like a Russian roulette. So I don't see any of the comments as assholery.
