> our social norms are influenced by the media
Sure. But they are also formed by our personal observation. If you would find out that lots of your colleagues, friends, family members and celebrities behave in 'strange' activities, those activities might not be perceived as strange after a while anymore.
Of course, you're right to point to the negative examples of Russia, Iran and Germany. Laws and norms can change both ways. This has been the case with antisemitism. It used to be quite accepted to be Jewish during the Second Reich in Germany but wasn't anymore in the Third. As another example, as far as I know, the Dutch had census data about the religion of every citizen, which only became a problem when they became occupied by Germany with its laws against Jewish.
But what now? Its all to easy to imagine a future with hardly any privacy. How will it look like? How should it look like if we take the end of privacy as a given, at least as a gedankenspiel.
