It's about trust. If someone is trying to find out what I'm doing, I'm going to hide what I am doing because they are acting suspicious. The more asymmetric the power balance, the less trust can exist. A less biological, more modern concern, is that a potentially super-intelligent actor (e.g. an ML team dedicated to finding human weakness and exploiting it, like marketing depts do) could find out things about me that even I didn't know and use it against me. In the modern world complete paranoia and distrust in is the only strategy with guaranteed sucess which respects our drive to survive. Mass-manipulation of elections is a symptom of the disease.
