> Why should you "own" data that happens to be about you?
We are on a rock hurling through space at millions(?) of miles per hour, depending on your frame of reference. We literally write our own laws, in order to shape our destiny as we see fit. Or, we used to anyways.
An entity like Facebook having so much data on such a large portion of the population (not just US citizens, but citizens of the entire planet) merged with the increasing power of big data algorithms and understanding of human psychology is a very dangerous tool of persuasion.
Personally, I happen to believe that the reason this risk is suddenly getting so much "public support" is because politicians have come to a bi-partisan realization that having an independent entity with this much propaganda power is dangerous - the bi-partisan aspect is interesting as I think it's fair to say silicon valley "leans left" and would tend to be more favorable to democrats, but the last election demonstrated the risk inherent in that stance. Hence, a "spontaneous" flood of newspaper and TV articles with the subsequent (in my opinion, would be interested to hear disagreements on the chicken and egg aspect of it) awakening of "public outrage".
