it very easy to ruin other aspects of your life like your relationships, your public image, and can run you afoul of the law.

Not when you succeed to the level that you can ignore the laws - which isn't just one man in the US, not by a long shot.

Anytime, and incase you missed it: I'm not just talking about AI driven vehicles. AI driven decisions can be just as harmful: https://www.politico.eu/article/dutch-scandal-serves-as-a-warning-for-europe-over-risks-of-using-algorithms/

Sure, the internet is more practical, and the odds of being caught in the time required to execute a decent strike plan, even one as vague as: "we're going to Amerika and we're going to hit 50 high profile targets on July 4th, one in every state" (Dear NSA analyst, this is entirely hypothetical) so your agents spread to the field and start assessing from the ground the highest impact targets attainable with their resources, extensive back and forth from the field to central command daily for 90 days of prep, but it's being carried out on 270 different active social media channels as innocuous looking photo exchanges with 540 pre-arranged algorithms hiding the messages in the noise of the image bits. Chances of security agencies picking this up from the communication itself? About 100x less than them noticing 50 teams of activists deployed to 50 states at roughly the same time, even if they never communicate anything.

HF (more often called shortwave) is well suited for the numbers game. A deep cover agent lying in wait, potentially for years. Only "tell" is their odd habit of listening to the radio most nights. All they're waiting for is a binary message: if you hear the sequence 3 17 22 you are to make contact for further instructions. That message may come at any time, or may not come for a decade. These days, you would make your contact for further instructions via internet, and sure, it would be more practical to hide the "make contact" signal in the internet too, but shortwave is a longstanding tech with known operating parameters.

Photo made with AI, and that's not Alligator Intelligence.

The point is: IP addresses that download the content are traceable (and spoofable, but that leaves trails too...) Yeah, you might be one of thousands, but every day you log in you increase your odds of being spotted.

Listening to longwave radio? Yeah, basically anybody anywhere on the planet with a receiver. Even local broadcasts it is nigh impossible to know who is listening where within the broadcast radius and the average person walks around with several radio receivers on them all the time now.

What a way to advertise your impotence.

Noem is no dumbass, but she plays a convincing one on TV.

Oh the legal system is pretty good at deciding intent

I wouldn't say it's good at determining actual intent, just good at deciding what intent is going to be assigned by the system.

If you send an encrypted email over Hamlink once, or say something like “Beefy Burrito this is Enchilada, the tamales are in the basket” on 33cm once, probably nobody’s gonna notice.

I've always wondered how much steganography is in practice - if it's being practiced well, nobody knows. Setup a HAM station that snaps a photo at sunset and a couple of other random times per day. Transmit the photo in a standard, open digital mode, but hide your message in the noisy lower bits of the 3 color channels 0-255 R G and B, you can easily modify 6 bits per pixel without visually distorting the image, drop that to 1 bit per pixel and nobody who doesn't know your scheme could ever find it. To the local hams, it's three chirps a day, with a reliable pretty picture of the sunset and a couple of more varied times. As a utility channel, that's three opportunities per day to secretly communicate something to a listener that nobody can identify. If the picture is just 2MP, that's 250kBytes of bandwidth per image.

If you want to secretly communicate with people, use Reddit, or the Fediverse.

Absolutely, though the "listeners" there are more readily identified, even via Tor.

difference is intent.

And intent is functionally impossible to prove, but endlessly arguable and a judge can make a finding based on their judgement - something very different from proof.

send a PGP signed message over ham radio; if I understand correctly that’s basically a checksum that can guarantee the sender’s possession of a private key.

Correct.

If you intend to practice the hobby, get the license. I let mine lapse after 10 years because I don't practice anymore, but I generally still remember the basic rules and how to operate the gear, so if I ever had an emergency need I'd use what I had access to - but I haven't transmitted anything in years and years.

Most actual communication is illegal on the ham bands one way or another

Except in case of emergency, natural disaster, etc. Before we carried cell phones, I had ham handhelds that we would talk directly to each other on 70cm for the usual "Hi honey, I'm on my way home" or... in the days before cell phone lots existed at airports, I'd call her on the handheld to let her know I was approaching the passenger drop-off/pickup area at the airport after a flight so she could start going there from whatever makeshift staging area she was in.

Anyway, when we would be out in the woods, we could reach each other roughly 1/2 mile like that from handheld to handheld, but if we ever had a serious problem we could switch to 2m and hit the local repeater which would get us more like 12 miles of range and coverage all the way into town where there was usually somebody who could make a 911 call if we needed it.

So, yeah, we have cell phones today, and they work when they work, but I find that when the cell phones don't work (like during / after a hurricane) the ham bands generally are working - or at least are restored quicker, and nobody is going to press charges for emergency communications on the ham bands.

If you want to use the ham band for instacart dispatch coordination, yeah, you're gonna get more than static about that.
