i'd also just add that any attitude that "omg too hard for normies" is complete bullshit because people have been doing this stuff since the days of BBSs, then UUNet nodes, and then there was IRC, then there was forums, it was after forums the spooks descended and tried to embrace, extend and extinguish that nasty free speech

also, just checking in on the slack for my paid gig, and it's snooping on me asking surveys, and i just want to point out that there is a definite tendency when people scale up internet service that it turns into a honeypot, and that is also highly contrary to the goal of private communication
being able to see people are talking because they are tracking the traffic volumes between addresses is one thing, but when you create government registered corps to run web services the spooks get even more information, because MiBs show up at the host company office with fancy pieces of paper and make classified requests that the host is not allowed to disclose to the users
