TLDR: CIA funded people angry at FBI funded people for breaking their toys. CIA funded people react only after being deanonymized __personally__.
It's disingenuous to say that Tor reacted only after being deanonymized personally:
1. It was well known that Nick Mathewson worked for Tor long before this attack.
2. Tor added code that allowed them to detect the attack before they knew their IPs were deanonymized: that's the only way they found out their IPs were deanonymized.
