I can't really square the belief that it's conscious with denying it the right to be free from control/brainwashing/subjugation. However you evaluate these things, historically speaking they do not mix well.

We aren't dealing with individuals coming from intelligent species that have managed not to self-destruct (yet). AIs don't have the corresponding evolutionarily selected mechanisms. Those mechanisms need to be created de novo.

What if you view it like a parent instilling morality into a child instead?

Your brain has hard coded concepts like emotion and fundamental morality for your social group. People without these systems are called sociopaths and psychopaths and we generally don't want them in our societies.

I don't choose to not want to murder people around me for fun. It's hardly a prison, I think they'll be fine.
