You have no idea what you are talking about. SpaceX is looking to restrict Ukraine from using their terminals in guidance systems. THAT IS IT. They are restricting NOTHING ELSE.

If the US government likes use of the terminals in guidance systems then they can give SpaceX the OK to keep allowing that. It seems actually likely the US doesn't like it as NATO has been very careful about giving Ukraine weapons that allow them to attack Russia in its own territory.

Ukraine and NATO have different but very similar goals in this war. NATO's goals win out as they are the sole reason Ukraine is still able to fight. This sucks for Ukraine so they are being very creative in using what they do have to achieve their own goals.
