It sounds like there were over 15 people in on the scheme. At some point people noticed that there was some wi-fi network called "STINKY" and rumors started circulating about it. It took a while for those rumors to reach senior command. Then they changed the name to make it look like a printer, which further delayed the investigation.
It doesn't look like they actually scanned for the access point. I suspect that's because it would be hard on a ship. All the metal would reflect signals and give you a ton of false readings.
They only eventually found it when a technician was installing an authorized system (Starshield seems to be the version of Starlink approved for military use) and they discovered the unauthorized Starlink equipment.
The Starlink receivers have gotten fairly small. It seems like that was pretty easy to hide among all the other electronics on the ship.
That seems unlikely, since the constitution doesn't really include safeguards against someone like Trump.
The founding fathers were afraid of a King (at least some of them were). They put all kinds of limits on the power of the executive but they assumed people would follow those rules. They never really considered the possibility of a private citizens gaining so much power that they can ignore government.
