Can't speak specifically to Cuba, but at least some of the countries glorified by tankies are nice only for a privileged foreigner on a short vacation. It's not like they'd protest against the government there to get arrested, and if they do, their country will be very focused on getting them out. They likely won't speak the language to understand what's being said in the media day to day. They also wouldn't live the life of the average citizen able to feel the weight of lower incomes and other quality of life issues associated with the government taking too much for itself and leaving little for the people. If they're a minority and they can keep it to themselves, they probably will "out of respect", thus no consequences. It also doesn't help when they're a tankie who thinks there's no problem with China or Russia isolating themselves from the rest of the internet for example, but even so, it's relatively easy when it's brief, not something you inescapably put up with every year.
Edit: I'm also reminded of Hasan visiting China but then comically asking "can I be out with this Chinese flag?" or something like that, as if his subconscious was telling him that even something as trivial in the West could get him in trouble there. It's evident he was being very careful, if not self-censoring.
