The ones I have seen arguing about it the most, about it being fine that everyone stays, aren't those in the situations you describe. Normally those ones just want to stay themselves for other reasons but don't argue against the ones who want to leave. They just wish that when the time to leave comes people will be able between leaving or staying individually.

I don't really care if the people here leave or stay, neither about their reasons for it. But I have to leave and will do as soon as the chance arises. I'm not going to give up my world and life just because some people have gotten comfortable being guinea pigs.
