Another way to think about it: privacy stayed constant over time, it just shifted from the family, local communities, and the social oversight (“eyes on the street”) that came with it, to big tech and government.
2) In the any tight knit community or town privacy is equal and non hierarchical. I know about you and you know about me and everything is good or at least tolerable.
This is not comparable in any way to the completely asymmetrical big tech/government surveillance (and consequently manipulation) that is happening.
Information is power and asymmetry of power is domination.
