Middle Eastern countries are not able to convince e.g. the US or any of the European Countries to extradite their citizens (or sometimes legal residents) for violating the moral codes of let's say Saudi Arabia or Afghanistan.
Because these countries know that (and becaue of diplomatic consequences) the law and/or government there doesn't even try it. But if the CEO of a porn site travels there he can and most likely will be held accountable. Tha
If it's a crime in both jurisdiction prosecution is certainly a possibility and happens regularily (or both countries cooperate to convict people without extradition)
Ultimately the United States have a lot more diplomatic sway over the world than some random country and that's why they can and do ask for a lot more.
If you ever need an example of everday US soft power that it is.
