I mean the advent of business computing was very literally the systematic eradication of 6 million Jews.

IBM's custom designed punch cards and the absolute openness of census records (church books are rarely encrypted) was the only reason the third Reich was ever able to census all European Jews and then systematically deport them in any reasonable time frame.

That is obviously very different from new WhatsApp TOS, but this incredibly prevalent opinion of "Well, nothing really bad regarding privacy and tech did actually happen, right?" irks me a lot.
