To move money out of an authoritarian country, you have to know someone who wants to move money in. The only reason it works at all is because the total amount of Bitcoin doing this is comparatively very small compared to local corruption and mining which can support this use case.
To make this transaction someone else in your local authoritarian country has to have Bitcoin, and be willing to exchange it for local currency. It's no huge surprise a lot of mining power ended up in China, because of course this is a transaction you do not want to do in China: you want to originate Bitcoin and then get some Americans to pay you nice clean USDs into bank accounts outside of China.
Which of course works because electricity consumption in China is relatively unsuspect (or was: naturally China has cracked down on this and is having ongoing power shortages to boot).
Which of course creates a weird compromise: if Bitcoin is good at getting money out of authoritarian countries, then either you're outsourcing to someone who can move currency around locally, or you are outsourcing an increasing fraction of the Bitcoin mining compute, and thus control of the network.
