Privacy is an ancient idea about maintaining a facade. In public you had to pretend to be god-fearing, support the king and government and be a paragon of virtue in all things. Behind the facade - in privacy - you could beat your wife, mistreat your animals and servants, indulge your sexual desires regardless of whether they were consensual and generally use your power to bully everyone.
Privacy kept corrupt governments in power. Privacy allowed companies like Intel to bribe others not to allow a fair business playing field. Privacy allowed people like Savile and Harris to abuse their positions of influence. Privacy allowed sexism, racism and eugenics free rein.
Privacy is the scourge of good people everywhere. We should be using technology to tear it down, everywhere it exists.
