The article is a bit older, but metadata analytics can be used to "unveil" the key conspirators that led to what we today know as the "American Revolution"[1] - please note how little data they use to find out who calls the shots, and whom you might want to disappear if you wanted to keep the colonies closely aligned with George III.

Widespread enough, this can be used to find dissidents today, suppressing ethically legitimate uprisings against injustice.
