I'm still not entirely convinced that tor is as protected as people think it is.
There's only something like 6,000 exit nodes. It really wouldn't be that much money for the government to run thousands of them. If you monitor enough exit nodes and enough relays, you can start to statistically tie connections back together with timing analysis.
I don't know this to be the case for sure but I can't imagine the government hasn't pushed towards breaking the security and identifiability of the tor network
I've suspected Tor of being heavily compromised for a while now. It's already known that many onion sites are government honeypots, with sites being taken over rather frequently, sometimes without triggering the canary. While it's better than nothing in some situations, I don't think it can be relied upon for true anonymity anymore.
If you read a lot of news, it's really clear Tor isn't protecting anyone from the FBI. It's about as effective as using limewire at this point. Which also, the reporting makes it pretty clear it's not effective to hide criminal acts in the least. But it's pretty great abusers think it's effective so they get caught.
It's not as protected as people think it is. This has popped up on headlines for years. It helps, but if someone really wants to find you on there, they can. It's just not as easy.
