Rättegångsbalken does have a provision that a prosecutor can order you to preserve information you already have saved for a maximum of 180 days (https://lagen.nu/1942:740#K27P16S1). I can't find anything about what the punishment for ignoring such an order would be, but to say a company could be forced to keep operating seems extraordinarily unfounded.
Given Mullvad I think they'd rather shut down.
“Entirely” possible? Sure, I guess it’s “entirely” possible that the NSA is actually controlled by a reptilian, illuminati cabal of extraterrestrials, while we’re just making stuff up without any factual basis whatsoever.
And furthermore, I am sure you know that when dealing with matters of security, it pays to exercise precaution and be wary of scenarios you cannot prove to be happening at the moment. E.g., you don't know your new friend you met at the bus stop is secret police, an informant for the Vichy government, but until you're damn sure he isn't then you don't let him know the location of your resistance safehouse. You don't need to have proof that your new friend has done anything wrong to be cautious of that possibility.
It's not very likely though.
If you can't even remember things in the medium term that's a level beyond "trapped in a dream" that's much more hopeless.
So, with that assumption, you make a computer solve a problem that's impossible for a human to work through in a practical amount of time. And then you verify it got the right answer. This proves the math wasn't done by your dreaming brain. (At least it proves it to a pretty good certainty, and you can repeat the test.)
Many NP-complete problems are good candidates here for slow solutions and fast verifications.
Also for situations that have the standard dream level of fidelity, you can try basic reality checks like putting your finger through your hand or more conspicuously spinning along your own axis.
I thought this was just me! There have been times when I've "read" in dreams (signs, usually), but I don't actually visualize the words. I just "know" what they say.
I would even say "highly unlikely". I revisited how I understand "unlikely" after reading this:
> Radioactive capsule that fell off truck found in Australia... Radiation Services WA general manager Lauren Steen describing it as a "highly unlikely" scenario.
Service might not collect data but they could be forced with warrant to start doing so for specific entities.
This has happened in Finland, for example.
