Foucault's style is (possibly deliberately) obtuse, and his knowledge of history dubious at best, per Keith Windschuttle's book The Killing of History: http://www.amazon.com/The-Killing-History-Theorists-Murderin... .
It's the question of why we all let this happen without any resistance
Because it's easy, because most of the time it doesn't affect us, and because it's hard for one voter to fix the problem. Bryan Caplan's The Myth of the Rational Voter is very good on this subject. Most people (and voters) don't even know how many Senators their state has, or their terms, let alone why complex subjects like privacy are important. Based on Caplan's book, I think ignorance is a more reasonable explanation than a fear of being anti-authoritarian or an institutionalized mindset.
This is a hilarious comment, given that Foucault's History of Sexuality contains almost no citations!
If you are interested in why Foucault ought to be a laughingstock, see Windshuttle's The Killing of History: https://www.amazon.com/Killing-History-Literary-Theorists-Mu... or the many essays Camille Paglia wrote on him. Her latest book has a reprint of "Review: Junk Bonds and Corporate Raiders: Academe in the Hour of the Wolf."
