I don't like to blame the tools, but Facebook was used in this way by Trump and the Russians. So there is a current day example. That said, claiming these are "mass surveillance" apparatuses is quite some rhetoric. While they can be used for this, they also have many other users. The were not created to be state surveillance and routinely fight state control of their data.

Like all powerful technology, I don't think trying to ban it is the answer. Rather, stronger regulation over how it's allowed to be used.
