Astroturfing, psyops, and disruption of general trust (commercially and maliciously, both domestic and foreign)

It is disturbing to me how unconcerned everybody is with this over what is still only a hypothetical problem. States and businesses have been long employing subversive techniques to corral people towards their goals, and they all just got an alarmingly useful tool for automated propaganda. This is a problem right now, not hypothetically. All these people aching to be a Cassandra should rant and rave about that.
