Vought has no way to control their superheroes?

This seems so implausible. I've been waiting for some big reveal that there's a kill switch Vought created, either genetically or simply implanted tiny bombs in all the supes' brains. They've been in the business of making supes for decades. Surely they would have felt the need to develop safety protocols to prevent a crazy supe from destroying everything. If a supe goes insane or can't control their powers or is working against the company trying to destroy them there's nothing that can be done? I know Vought is supposed to be the evil and greedy corporation but they're also supposed to be smart. They would have a way of keeping the supes in check.
