Yeah. It's notable they didn't crack the crypto. In the 90s when I was a young cypherpunk, I had this idea that when strong crypto was ubiquitous, certainly people would be smart enough to understand its role was only to force bad guys to attack the "higher levels" like attacking human expectations of privacy on a public channel. It was probably unrealistic to assume everyone would automatically understand subtle details of technology.

As a reminder... if you don't know all the people in your encrypted group chat, you could be talking to the man.
