Like i said in the other thread on this ship, what they want doesnt matter. They will be getting off that ship simply cause it's old tech, they admitted they can't sterlize something that big anymore, and it's a giant beacon for slavers if we just give them supply and medicine and let them be since it's a Generation ship, not a capital ship, and has no weapons. It's a slavers delight to board that ship and enslave everyone.
Their best choice is, since it's their ship, join modern society. Once that's done, sell the ship either as a tourism spot or museum piece, and if they want, buy a new modern megaship with all modern tech, medicine, galaxy map, crop techniques for long term flights, and even an FSD. Plus weapon capability and likely a fighter bay to defend against slavers should they wish to go back to their isolationist life. Plus they'll be informed of threats that can come from nowhere such as Thargoids and Guardians. Like it or not their choice is to live and at least be part time in modern life, or go on their way and be doomed to enslavement from a skilled pirate/slaver.
