I don't know the exact details of their setup but I would imagine if they have phones on the ship there's a network they can connect to on the ship that's not their starlink internet.
Aside from being able to possibly identify the starlink waveforms with passive RF surveillance or being able to identify the location of the ship through hacking spacex or their satellites, if they went back and forth between being connected on their phones to the ship network and the internet, their phones could have been compromised, leaving the possibility also of them being a perfect pivot point for hackers interested in exfilling important government secrets.
Overall just very bad opsec for a ship and definitely not a good idea.
Think some HRT femboys do consider themselves cis. At that point tho imo it's just a matter of personal labels since they are definitely non conforming
