The only way you can do this, is if the only service you use the provider for is storage. Encrypt the data before you send it to the provider and then they don’t know what they’re storing.

If they have to do any processing on it at all, then conceptually they need a plain text copy of it to feed into the CPU. And if they have that, there is nothing you can do to stop them from stealing it or using it.

There has been some research in this field, the concept is called homomorphic encryption. That is where you encrypt something in a way that allows a third party to manipulate the data without possessing a key. It is still very limited, and likely always will be due to the extreme difficulty of the question.

with an outside control interface that’s quite literally about as optimal as it can be.

Which is probably true, as long as you make one assumption- that the operator dedicates a significant amount of time to learning it. With that assumption being true- I’ll assume you’re correct and it becomes much more efficient than a Nano/Notepad style editor.

I’m happy to concede without any personal knowledge that if you’re hardcore editing code, it may well be worth the time to learn Vim, on the principle that it may well be the very most efficient terminal-based text editor.

But what if you’re NOT hardcore editing code? What if you just need to edit a config file here and there? You don’t need the ‘absolute most efficient’ system because it’s NOT efficient for you to take the time to learn it. You just want to comment out a line and type a replacement below it. And you’ve been using Notepad-style text editors for years.

Thus my point-- there is ABSOLUTELY a place for Vim. But wanting to just edit a file without having to learn a whole new editor doesn’t make one lazy. It means you’re being efficient, focusing your time on getting what you need done, done.

A text editor that doesn’t need a tutor because the interface is intuitive enough that someone who has been using text editors (as a concept) for years can more or less instantly pick it up and start working without needing a tutorial to simply edit a config file.

Yes exactly. This is a big part of why some repressive countries are starting to require identity registration in order to participate in social media. Arresting people is unnecessary if you can simply stamp out non-preferred speech at the point of discussion.

All the crypto in the world won’t help if you do stupid stuff and have crap OPSEC.

A big part of that is stay under the radar. If I were NSA I’d be running a great many TOR nodes (both relay nodes and exit nodes) in the hope of generating some correlations. Remember, you don’t need to prove in order to raise suspicion.

So for example if you have an exit node so you can see the request is CSAM related, and you run a bunch of intermediate nodes and your exit nodes will prefer routing traffic through your intermediate nodes (which also prefer routing traffic through your other intermediate nodes), you can guess that wherever the traffic goes after one or two relay hops through your nodes is whoever requested it.
If you find a specific IP address frequently relaying CSAM traffic to the public Internet, that doesn’t actually prove anything but it does give you a suspicion ‘maybe the guy who owns that address likes kiddy porn, we should look into him’.

Doing CSAM with AI tools on the public Internet is pretty stupid. Storing his stash on cell phones was even more stupid. Sharing any of it with anyone was monumentally stupid. All the hard crypto in the world won’t protect you if you do stupid stuff.

So speaking to OP- First, I’d encourage you to consider moving to a country that has better free speech protections. Or advocate for change in your own country. It’s not always easy though, because sadly it’s the unpopular speech that needs protecting; if you don’t protect the unpopular stuff you jump down a very slippery slope. We figured that out in the USA but we seem to be forgetting it lately (always in the name of ‘protecting kids’ of course).

That said, OP you should decide what exactly you want to accomplish. Chances are your nation’s shitty law is aimed at public participation type websites / social media. If it’s important for you to participate in those websites, you need to sort of pull an Ender’s Game type strategy (from the beginning of the book)- create an online-only persona, totally separate from your public identity. Only use it from devices you know are secure (and are protected with a lot of crypto). Only connect via TOR or similar privacy techniques (although for merely unpopular political speech, a VPN from a different country should suffice). NEVER use or allude to your real identity from the online persona. Create details about your persona that are different from your own- what city you’re in, what your age and gender are, what your background is, etc. NEVER use any of your real contact info or identity info.

Mainly conflicts with mDNS. However it’s shitty IMHO that the mDNS spec snarfed a domain already in widespread use, should have used .mDNS or similar.
