According to Elliptic, the alleged Chinese spies used Wasabi CoinJoin before bribing a U.S. agent (who I guess was actually a double agent?).
This is an important case to follow: I imagine there'll be a lot more pressure on Wasabi because, of course, 18th Century pirates used gold coins and therefore everyone in the 18th Century who used gold coins was a pirate, amirite.
