Turkey has a similar thing since about 10 years and the way it works is that if you don't agree with the government censorship you simply use some other DNS. Some service providers go the extra mile and block the ip but it seems pretty random. Even when blocked, you can use VPN. However, being able to access if you try hard enough is not O.K. Especially commercial operations are not viable if the Government doesn't like you because you instantly lose the non-techies. Dangerous stuff, even if you completely agree with everything the current government does don't forget that governments change.
