It's one thing to study abroad and have the chance to exchange ideas of any kind with the people you meet and if you actually take advantage of that chance or not. But it's another when you bring a built-in censorship-system with you to a country that has a "mostly" (but for how long?) free internet. In that way even when you go to another country and have the chance to experience other culture's views on the world, everywhere you connect to the internet you will still be slave to the censorship that is put upon you.
