Yeah, they are looking to attract your talent. Countries make these kind of concessions all of the time. Ireland for example offers low tax, that's why the tech industry likes to have their headquarters here, otherwise they would just go to somewhere else. I see it as a smart move if I'm being honest.
That being said, I remember reading somewhere else, that at one point they were 'selling' passports for Bitcoin, which is a differen't sort of vibe, not so sure about that. I would wonder how hard it is to get a passport anyways, if you were to just apply for one?
