Yeah, that does not surprise me. I’ve heard ‘allegations’ before. It is also known that the USG has set up ‘honeypot’ servers on the TOR network to attract and enable scanning of the traffic.
Some also think that the TOR network may be an advantageous ‘undercover’ way for some agencies to accomplish clandestine communications.
It’s not entirely secure, but it’s still better than the ‘open’ web.
