As Ukraine accuses Russia of terrorism with deadly strike on train, is Starlink helping Moscow target civilians?

If the Ukraine is using StarLink for military communications, that already is a big security threat. I’m wondering if some of those military communications are being leaked to Russia in advance of those drone strikes? If Ukrainian civilians are using StarLink, what’s to also stop their locations from being leaked too?

I’m surprised that there aren’t any sanctions forbidding any Western country from providing Russia with internet service.
