It's tragic that IBM built technology that helped enabled the death of large number of people. One thing the wikipedia page doesn't make clear was IBM aware of the atrocities? The article cites the 1933 census, but things in Germany didn't really heat up until Kristallnacht in 1938?
Anyway, the point was, things are not always black and white. IBM has certainly done some bad things, but it has also had a tremendous positive impact on society, medicine, techology, etc easily; more than 36m.
