Hah, yea, that's likely the case globally. More curious though for cases such as particularly problematic regimes. I know at least for awhile, FIDONet was a way that information flowed across firewalls because firewalls blocked TCP/IP traffic, but of course didn't filter traffic flowing directly over phone lines. Obviously radio has its own hazards as anyone who's ever done a fox hunt knows that locating the transmitter (or at least the antenna) is pretty trivial with a modest amount of equipment. But the optionality so that people can do their own risk assessment and decision making around it would be cool to see.

HF transmissions are much harder to locate than localized VHF signals. But yes, everything has tradeoffs.
