I find it curious hoe many big corpos maintain .onion services such as reddit and meta (with facebook)
Also, many nodes pass through countries such as the US, UK, DEU, NL and so on.
My rule of thumb is that if something is allowed to operate and exist in the imperial core that goes a bit counterintuitive to bourgeois class goals (specially today with surveillance) then it must have another purpose not easily discovered by the public.
I do think that the CIA (and any other secret service orgs in other countries) operates on multiple layers of the web.
Its also very common knowledge at least for the German secret service, that secret services are currently recruiting people who are skilled in IT, and hacking. They also train them. Also Data, is such a rewarding business for many. So never think you are alone on the world-wide-web (not to cause hysteria)…
