That reminds me of when I briefly worked for IBM - an unpleasant corporate culture. I don't think it has anything to do with the end results, however. i.e. good people still ended up working for them.
1.2 was problematic and 2.0 worked. 1.2 was Microsoft and 2.0 was IBM. From what I have read the NT team didn't want any of the MS OS/2 developers - this is just memory - and it was related to perceived code quality or something like that.
