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.
One reason they maintain nodes is for their infiltrated agents; They also maintain websites for that. I don’t know if that means they don’t also track you but they have self interest in having tor and keeping it alive.
It might be more likely if you own a node that you get CIA traffic on it…
