The $ins of $ilicon Valley - IBM: Prelude to Genocide
Long before the First "Horseman" Microsoft came along and set the stage for toxic Technoculture in America and the rest of the World; IBM helped contribute meaningfully to the Holocaust by allowing the German government in WWII to identify, catalog and kill millions and millions of people based on their religion, culture or sexual orientation. This was entirely preventable, but IBM looked the other way and has since still defended themselves.
As of now, IBM has suffered no meaningful consequences for their crime.
