I think we're talking at cross purposes. I (and presumably Musk) am talking about the Russian's targeting the starlink receivers / satellite dishes. These are (theoretucally at least) detectable using the same type of radio triangulation techniques used since WWII. Using one of these puts you in danger of attack if you are somewhere near it. And by attack I mean having a missile launched at you, being shelled, or having men with guns turn up on your doorstep. Hacking is not required.
