In order to keep order among the society, C30 uses a machine in the admin suite that has the capability of projecting messages across the entire ship— a protocol originally designed to broadcast abandon ship warnings.
C30 also has drones undercover all throughout society, that he uses to spread his propaganda, using a groupthink tactic.
C30’s strategy is to keep everyone busy with their—now mostly meaningless—jobs aboard the ship, making everyone believe that they are performing actions that are pivotal the continuation of society. But really, keeping everyone locked in on pointless tasks is the pointless tasks is the exact thing that keeps in power, which is what gives him the capacity to tell you what to do in the first place.
