Signal Media noted in early 2018 that the three largest economic zones on Earth differ significantly in how they treat privacy. Europe gives people the last word on how their personal data can be used – and imposes harsh penalties on rule-breakers. In China, it’s the government that has the real sovereignty over all data and information flows (Russia and Turkey are trying fitfully to do the same.)
But in the US, apart from some sector-specific exceptions such as healthcare and a general ban on deceptive trading practices, it falls to private companies to set their own privacy policies on their platforms. As Facebook and others have found out, profit-seeking, politics, and privacy don’t always fit together neatly.
