Feedback: darknet has come to mean places where you go buy drugs online, not p2p applications generally.
I mostly hear it used to mean what it is supposed to mean, but that is rarely from non-technical people.
Darknet now: Anonymous place drugs sometimes happen
Darknet if it becomes bigger: That place where terrorists and criminals hide, the FBI and NSA say it's a risk to national security and we have to stop it at all costs! What do you mean it's just a secure messaging app? I'm not a terrorist, I don't need anything like that!
Look at Tor.
