there is no such thing as internet in China, correct word here for North Korea 2.0 is intranet, it's like calling something with 20% milk fat content butter
There is a difference between China and North Korea's internet access. North Korea works on a "whitelist" basis, whereas China operates on a "blacklist" basis. The Chinese people have access to the majority of the internet but, for cultural and language reasons, are not interested in most Western websites. Yes, many western social media and news sites are blocked but they are not "the internet" and if you consider them as such then the west has exactly the same problem as the one you have just described.
please, i was living in China more than 5 years, Chinese government won't let me to video chat with my family, every single app was blocked unless i wanted my family to install Chinese spyware on their devices, even the Skype which is supposed to be not blocked is essentially slowed down to speed marking it useless for video
pretty much every photo sharing website is blocked
Chinese "internet" is essentially using white list, it's easier to say what's not blocked than list everything which is blocked
