This is essentially the case for Starlink

On the one hand, yes. That's why possession of a starlink terminal can get you killed in Iran.

On the other hand, Ukrainians are finding out that someone else is in control of that starlink infra.

i don't think anyone with enough money for shootin clusters of sattelites into orbit will be a free open internet builder. ofc thats an assumption. This network of sattelites would also need to join in and coordinate with other stuff up there, as far as i can tell its pretty crowded and theres collision risks etc.

Except Starlink won't hesitate to censor you as well as the Ukrainians are discovering.
