That’s bullshit, it’s fun just in different ways.
Sweden is coffee and biscuits while the US is cocaine with meth as a treat.
The system is all over the place, it’s safe for them to be drones, but if they show any potential they get fired up the railgun of intense academics like you can’t believe, they have some absolutely incredible engineers and scientists, and as a percentage of their population it’s almost unheard of.
The downside is after school they tend to leave for the US or elsewhere, the actual job opportunities for world-class scientists and engineers in Sweden are decent, but their yield of talent far, FAR outstreteches the economic capacity to carry them.
They have the talent pool of West Germany with the population of, well, Sweden (10.5m, it’s tiny).
2 things:
This has never been unknown, this is one of the fundamental attack vectors against TOR, the IM protocol seemed to make correlation easier due to its real time nature.
They added a protection layer called Vanguard, to ensure the internal exit nodes were fixed to reduce the likelihood that you could track a circuit with a small number of compromised internal exit nodes. This seems like it would help due to reducing likelihood of sampling.
Other state actors might try, but they’re not in the same league in terms of resources, IIRC there are a LOT of exit nodes in Virginia.
tl;dr - The protocol is mostly safe, it doesn’t matter if people try to compromise it, the nature of TOR means multiple parties trying to compromise nodes make the network more secure as each faction hides a portion of data from the others, and only by sharing can the network be truly broken. Good luck with that.
