I guess you might also find when people start getting ill the ship mysteriously has an outage of internet. I bet much like on an airplane, the Captain gets to decide if it's on or off for the passengers. Having a Starlink is a bypass. When you don't want people seeing CNN reporting the latest about which countries and ports turned you away, you want to turn off the internet to prevent the potential for mass hysteria?
Right as if that happens a lot. I'm sure it's just about their bottom line.
And you can't keep information secret anyway. In case of a quarantine people would be locked in their cabins. Better to have them have the information.
Besides, I'm extremely anti-authoritiarian, I would be the first to start a mutiny. It's another reason I wouldn't want to go on a boat, I don't take orders.
