The way Starlink or any other satellite constellation works would be either destroyed in functionality by being removed from said constellation, they can only connect to a larger network or satellites for their functions to be useful, or the country’s control over a few of the total would be functionally useless. The best option in that veign would be for SpaceX or whatever company runs the constellation to be owned by all governments proportional to their population but that would have issues where countries like Russia, China, the US, NK, and Israel would then have more access to the constellations to spy on all people and censor everyone world wide more directly. I don’t think that would work it would make things worse most likely and would be completely unfeasible. I think a non profit something along the lines of the ACLU but world wide running it for the benefit of humanity with privacy, freedom of speech, and that sort of thing in their charter while being functionally immune from state/government interference while operating under those parameters would be the most feasible solution which would be ugly but maybe better, maybe with the UN as the overall backer of the constellation management, making it a more powerful entity but stopping the US, China, Russia, France, or the UK from individually controlling the way the constellation is used, and forcing all countries in the UN to allow access to the free and open internet.
