@sickburnbro Sending paper letters is also tracked and allegedly scanned to the point of being able to be read inside. At least the encryption of Proton and Signal -- if the encryption is true and the software on either side isn't phoning home the "E2EE data" anyways -- is preventing half of what Google and the likes do.
Low-speed, long-range radios in a digital mode sure sounds like an interesting solution to all communication being a spy platform (if it's a computer running disconnected from the internet and only connected to a slow radio, it can't send much information where the operator would be unaware), but radio signals could be tracked and "encryption over the air is illegal" in most FCC terms 🤔
