Take a look on North Korea and their internet. It is limited, it is controlled (lol).
Their internet is highly censored. The pages you can visit are limited, let alone the services that accept Bitcoin. There is no reason for a totalitarian government, of that level, to get involved; they already control everything.
Even if I had high chances of getting away with it, I wouldn't even try, because there's a small chance I won't have a head afterwards.
