In the early days of WWII, or a bit earlier, an American 'computer' company set up digs in Germany. I expect it used punch cards in a very primitive manner. The information fed into the system included fine detail of German citizens, down to language spoken, native language, Jewish language knowledge, Jewish ancestors and Yiddish language skills. Written information flooded in from all over Germany and it was all put into this primitive computer system. Maybe even information from occupied countries was put into the database.
This collated information database gave Hitler all the information he needed in one database and we all know what then happened.
So who was this company and is it still around? Indeed it is. It is called IBM. That would be the IBM company that thoroughly screwed up Australia's last census and had to shut its online census site down for weeks from around 8pm on census night, just as people finished dinner and then went online to do their democratic duty. It was not a cyber attack from overseas but just the sheer incompetence of IBM. A few weeks later, I did eventually fill my census in with a lot of nonsense as a reaction to the scarily bizarre census experience, and that our data will be retained with our names. It seems I am now an unmarried hetrosexual without relatives. somewhat of a contrast to my last census data, where I was a gay man in a defacto relationship with many relatives.
Of course if you were a homosexual in Germany in 1939, that would have gone into the database too and many suffered a similar fate to the Jews of Europe.
So, a company that complicity worked with Hitler and sorted and collated the information he needed for the Holocaust to happen, and without doubt knew how and why the information was needed, is now a big and 'moral' company in the US. And our Australian government entrusted IBM with our census? Disgrace! That IBM was allowed to flourish in the US is a disgrace.
Trust IBM with your data? I don't.
