This doesn't happen on its own. This can happen through bad system prompts, a model that is trained to act maliciously or has been RL'd incorrectly, or prompt injection. All of these things are controllable, have solutions and countermeasures, and tie back to human responsibility.

This isn't a realistic world and will literally NEVER happen. No will only ever mean no for the general public, and yes for a privileged class. So by fighting for this you're actually just fighting for humanities (and your own) enslavement and for the big labs to succeed in hoarding all of the power for themselves. That's the issue with the "no" camp, they're actually just serving as useful idiots for the labs who know that "no" is not even in the deck, and so they know that they can use the "no" camp to act as extra cannon fodder.
Now people who are actually fighting for decentralization of power are left to contend with not only the labs and their hundreds of millions of dollars, paid for celebrities and politicians, and a fleet of self-interested and bribed NGOs, but an army of clueless "no" foot soldiers who think they're fighting for a possible outcome that will actually just be serving the labs themselves. Meanwhile, the leaders of these well organized "no" movements are quite aware of this and taking kick-backs themselves.
Even in a parallel universe where it outwardly looks like "no" has won, every single nation on Earth is going to develop AI in underground labs despite outwardly flexing they are not, no matter what they claim on the surface, and will use it to steer and control society. The only thing worse than being openly steered and controlled is when it happens without you even knowing it, whereby the decisions you think you are making are being made by someone else, and the opportunities you have in life are already decided for you based on factors you are unaware of.
