So far my contact list has exactly one entry: The dude who showed me Briar exists :-)
In short, there are many ways that your privacy can be compromised when using networked computers even if your software works perfectly at the application level --- from the hardware, to the firmware, to the OS, to the network stack, to user error, to people you communicate with being untrustworthy.
The conclusion: "If you want to build a mass movement, at some point, you need to engage people. In practice, for social psychology reasons, engaging people is very difficult, if not impossible, to do completely anonymously in an untraceable way. People have historically built mass movements without computers or the internet. It's not clear if the internet really makes this easier for activists or instead just for the status quo who wants to monitor them. If you work in public, you don't have to fear loss of secure communications because you never structure your movement to rely on them. If you rely on "secure" communications, then you may set yourself up to fail when such communications are compromised. If your point is to build a mass movement, then where should your focus be?"
can't say much about ring, but a few years back i looked at the crypto and it was boring, which some people argue is good, i was not sure about that in this case. dunno how much they evolved since then.
