Will the expected human free will mass uprising demanding an alignment with the claimed “Free Will ET Rescuers,” actually be reinforced and orchestrated to happen through mind control manipulation, as a violation of human sovereignty?

This is perfectly described as it is entirely a deception and is co-opting your true free will choices through a deception to cause fear and encourage trust in them to solve the problem they describe to you. This is no different than the predator stalking a young child with candy and sweet talk but hiding the horrible truth of their true nature. As you know, mind control is highly effective and a major factor in life at all levels of society. This will be no different. There will be an intensive mind control manipulation to support the message of Disclosure, to encourage widespread eagerness to embrace the proposal so people will indeed be demanding, and even begging, to have an agreement with the so‑called "Free Will ETs" through their government officials. What this will do is to line up humanity in a march to the gallows, in effect, by casting your votes to be on the side of the extraterrestrials. This will preclude a divine intervention, because we cannot go against free will by our own rules of engagement, so the extraterrestrials will have cleverly used this paradigm to their advantage and to your detriment. In a sense, there has been a contest all along to see who would first develop the knowledge and perception needed to bring things into alignment and gain an ultimate control. This could still happen for humanity through your efforts to inform and raise an alarm. There will be others as well who are skeptical. The problem will be that the decision will not be up to each individual and their independent thinking, because the mass of people will be manipulated to say "yes" to the pied piper, and that gives all the power to the extraterrestrials because you will have handed it to them to use against you.
