1) The CEO example isn't really a good one to me, given the wealth inequalities in the world, leaking CEO's salary is almost desirable... I tried to read the blogpost and paper about mobile data location. At one point they talk about aggregated data, but then in the paper : "This dataset is collected by a major mobile network operator in China. It is a large-scale dataset including 100,000 mobile users with the duration of one week, between April 1st and 7th, 2016. It records the spatiotemporal information of mobile subscribers when they access cellular network (i.e., making phone calls, sending texts, or consuming data plan). It also contains anonymous user identification, accessed base sta- tions and timestamp of each access.". So... the data is not really "aggregated"? The dataset literally lists some user IDs.

2) If I'm fired because my boss didn't like my history of movie, then it can probably be defended in court, depending on the country. I could also find another boss who has a natural sense of ethic and who doesn't judge me for what I watch.

Thank you for the links anyway. I will look at them again in a few day to see if I missed something
