Oh you sweet summer child. You really have no idea what living under a hostile government actually means. Your “uncensorable” networks work as long as as the state respects people’s freedoms and allows them to exist. It’s easy to be a “rebel” when you have nothing to fear. An ability to freely exchange and access information is what fascist totalitarian governments fear and fights against the hardest.

They won’t even need to break the encryption or censor it or anything. It would just be made illegal, and given that it involves radio transmissions - easily detectable.
