And that also doesn't fix the same cell use issues regardless of captured equipment.
Ukrainians at that time insisted they wanted it everywhere within their legal territory. I believe they have that now.

Other countries have changed ownership laws to get Starlink. A recent example is Indonesia, the opposite is Vietnam. If the Feds want thier military to have it they can get a waiver from the local government. Or just ask SpaceX to transmit anyway. You're essentially asking SpaceX to do in Taiwan what they do in Sudan. So there's no issue with Sudan from your POV
I know more about this stories than you do, sorry.
The issue in Ukraine is being fixed with a whitelist. It àllows Ukrainians to buy individually, use it behind enemy lines, supply comms to partisans, use in baba yaga drones etc
