#2i'd love to see some grassroots-powered clandestine para-web running at least partially on radio. obviously such a project would either immediately or at some point face the usual issues like: spam, cp etc. that's why i believe such a network would have to be slow. it would have to be so slow (and just fast enough) for text-based communication and simple protocols. and i mean text as in < 1kB ... not sufficient for transmitting sth like base64(videoclip). that would be so cool.

Internet via Ham Radio aka Packet Radio is a thing: https://themodernham.com/ip-over-ham-radio-via-new-packet-ra...
Pair it with the Gemini protocol and you're there: https://en.wikipedia.org/wiki/Gemini_(protocol)

Isn't ham radio no-encryption-allowed, no-commercial-use-allowed?

It is. That doesn't disallow mesh networks, but Gemini would be off-limits due to TLS. Gopher would be OK.

Signatures are okay though.
And you can do encryption, when you have to control remote devices which belong to you.
and internet still can be non commercial.

Reticulum qualifies as that. It’s designed to run over LoRA. (The radio protocol, not the LLM thing.)
Re: Practical Radio Circuits (2003) [pdf]
#9You can pick up a pretty reasonable amount of radio signal with the right length of wire and a properly tuned LC circuit tank.
I didn’t believe it until I tried it, but it’s a surprisingly good first pass at an FM frontend.

Sort of, yes, but it's quite a bit more nuanced than that.
The actual rules say you're not allowed to obscure the meaning of a message. Use of encryption itself is not specifically prohibited, but you're not allowed to hide the information being sent. So, "encryption" is technically allowed for things like authentication and signatures, under most interpretations of the rule.
It is correct that you're not allowed to use your ham license for any commercial purpose. But again, there are narrow exceptions: a teacher getting paid to teach a class on amateur radio or science in general can transmit to demonstrate the technology, or an astronaut or military member making contacts with amateurs for goodwill purposes or as part of an exercise.
