Holy moly! Good to know, I really wanted to visit China in the near future and I will be aware of it while enjoying my time there.

I think when you go to China you must have with you your "fiat phone", the one with Google all the KYC shit. So you just enjoy your time there, but to access the "alternative world" you bring with you a RPi Zero W with Arch and all the CLI tools (WeChat for IRC, a future Nostr CLI client and so on, Neomutt for your Protonmail/Skiff/Tuta and so on), any problem you think you might get yourself into, you just fry and destroy the encrypted MicroSD with the Arch image and all your CLI/TUI setup.
