Theres a difference between totalitarian states and regular dictatorships. Russia is a dictatorship and so is China, but for the most part as long as you don’t get involved in politics the government will leave you alone.
North Korea wants to control every part of your life and mind, which is a different level of dictatorship. Like I said, when people escaped from North Korea into China, they were amazed at how much freedom people living in a Chinese dictatorship had.
The same thing happened in the USSR. North Korea would lease slave labor to the USSR. When people saw how much higher the standard of living was in the USSR, they would commit crimes so they could get sent to a soviet prison. Life in a soviet prison was better than life in North Korea.
One way they do it is they cut power to an apartment complex. Then they go into everyone’s rooms and see if there are tapes in the VCRs, or DVDs in the DVD players, etc. since you can’t eject them when the power is cut.
North Koreans have found some ways around this though. They use Notels so they can put a DVD in the player while watching South Korean movie off of an SD card or USB drive. Then if the power gets cut and the inspectors come in and notice the notel engine is still warm, they just say they were watching a North Korean DVD.
Also my understanding is the official will rummage your apartment looking for foreign media.
I don’t know a lot about Turkmenistan, but this is my understanding.
North Korea has its own national internet that is disconnected from the global internet. Turkmenistan has a global internet that is heavily surveilled. You can still access the global internet, its just dangerous (same as in Iran, China, Russia, etc)
In North Korea if you watch foreign media you (and your family) get sent to a concentration camp or executed. In Turkmenistan you get a warning.
