Ukraine is under martial law, so privacy rights (especially involving something like MAC addresses which Starlink already has, not to mention that most citizens still in country can’t afford it in the first place) are far down on the list. It’s an unfortunate cost of Russia’s invasion. The Ukrainians have already done similar things with cell-based devices, it’s not some massive undertaking that would be new to them. It’s not like they’d make it front page news, either.

Really, it’s not even just Ukraine that could do something. Starlink can too, but because maintaining lists has no ROI they won’t until they’re forced.
