Also, in emergency situations regular FCC rules are suspended so encryption is not a problem. We actually used this mesh to provide internet to hams working emergency communications in a fire zone after their internet lines were burned out.
Also good point about emergencies and backups.
The prohibition on encrypted content is a deal-breaker for me, and a lot of other people, who might otherwise want to experiment with connecting to the Internet from difficult locations.
But since the Internet runs on encrypted protocols now, using unencrypted amateur radio transmissions potentially means eavesdroppers and man-in-the-middle attacks, so you can't do anything sensitive or personal, or even anything requiring login credentials.
And since hams are very likely to narc, snitch, or grass on you to defend the sanctity and integrity of their hobby, you can't do anything interesting or unusual for long before someone finds a rule that forbids whatever it is you were doing and forces you to stop.
You forgot rats and stool pigeons. It really detracted from the extremely important point you were making.
It may be different in your locale, but the hams around me are mainly older white men, and the voices that can be heard on the air are frequently strongly biased against my moral and political opinions. And they have no "block" buttons.
