GPS is quite a bit different. The satellites just orbit and send the same information out. The user device doesn’t have to send anything back - the “communication” is only 1-way. Also, GPS is significantly further out from the planet and involves a lot less satellites, so it is not really feasible to turn them off specifically targeting a small area or an individual target - you’d have to black out a huge chunk of the planet to reliably block “an enemy” from using it.
Go check out who runs GPS. Starling being nationalized isn’t happening, but if it did the service would likely keep on keeping on.

And that is why Russia also uses GPS.
