Profilcracy:the power of the people vs the power of datacollecters

We all know that the word democracy comes form ancient Greek language and means power of the people.
But after discovering what kind of manipulation has done Cambridge Analityca in order to influence the vote of the Brexit and the election of american president Trump in 2016 I'm really doubting of the real meaning of the word democracy.
What does really remain of the the original meaning of the word in our times?
May be it would be  better  to talk about profilcracy!
Yes, it would be! Since the primary techonologic social firms own a lot of our data and they use them to profile us, in the best case just to sell our profiles to the web operating firms.
But in the worst we may become just target for untrustful politicians who just believe in power: the power of the pofilmakers; not the power of the people.
