I agree with the parent comment, each country should control the communications in its own airspace. Surely this is how it works? Starlink cant just start selling internet in countries it has no jurisdiction or communications license in?
That said, Starlink can be turned off on a per country basis, so the government can ask (or demand) that to be done. If they refuse, there may be consequences that can be escalated to a political level.
We're playing around with the word "should" here, but from a moral standpoint, I disagree with any opinion that a sovereign power should(morally) be able to control communication at all - short of immediate threats to public safety (yelling "FIRE!" in a crowded theater).
