Yep. Known issue.

For roughly $50K startup, and $30K/year, someone could reliably
determine most or all source and endpoint pairs, and also act as exit
node for a large portion of conversations. They would also speed up
the Tor network significantly. (100 nodes, high speed dedicated colo
lines purchased in bulk.)

Tor is nice against industrial espionage, but not against NSA or
"Firewall of china" level attacks.
