Just let Signal operate via Satellites and you are fine: https://de.m.wikipedia.org/wiki/Weltraumtheorie
They can ban that as well.
The only way anything can continue working in practice is if it’s decentralized, and served by different websites secured bu https rather than one app in one app store. Hard to take them all down.
Perhaps Moxie Marlinspike now better appreciates decentralization behind messengers. I have written here years ago as a response to him exactly this scenario: https://community.intercoin.app/t/web3-moxie-signal-telegram...
The thing with https of course is that the governments can insist that browsers include their backdoored certificates. But the browsers are large enough that it’s difficult to get them to do it. China’s Great Firewall probably can. But in order for that to happen they have to prevent packets encrypted with the non-backdoored certificate chain from being routed. That requires serious control over all the networks.
This is partly why I started Qbix. So people can host whatever they want on computers of their choice. Without this decentralization, the governments are two steps away from mandating ALL your voice conversations are scanned, transcribed and analyzed by AI at the edge. Microsoft Recall + message and voice scanning = 1 step away from total panopticon of everyone everywhere. And with superintelligent AIs doing precrime based on everyone’s conversations!
You’d need to roll your own mesh network — definitely doable in local areas but the question is how to connect them over wider distances without going through the Great Firewall. Satellites?
I use grapheneos and can create storage scopes so that the scanning app would only have access to files I deliberately allow.
Doesn't solve traffic analysis. Maybe some more advanced methods that encrypt over https could work.
Go make a protocol that fools all the AIs from every angle, that are scanning 24/7. They can get you on the metadata pattern alone, nevermind even the content.
