I was wondering something like this but in a different capacity.
What with certain countries (they know who they are) and their hatred for encryption, it got me wondering how people would communicate securely if - for example - Signal/WhatsApp/etc. pulled out and the country wound up disconnecting the submarine cables to "keep $MORAL_PANIC_OF_THE_DAY safe."
How would people communicate securely and privately in a domestic situation like that?
