To everyone who is concerned about government harvesting Signal metadata: All NATO members and some other countries do have 100% passive monitoring coverage of network flows for intelligence agencies. Once participating IPs are determined, your traffic will be correlated.
The only way to prevent that is to use a trusted mixer that would have too many inflows and outflows. Any distributed system is actually more vulnerable. Well at least until the storm the offices.
Alas, there's nothing really worth advocating to the normies of the world - I feel it's too early for them to adopt XMPP as a convenient-enough-for-their-expectations replacement.
If the normies *really* needed something *today*, I suppose they could pay an honest, reasonable price for an email address from an email service like posteo.net or purelymail (which support "autocrypt"), then use #Deltachat. Then use #linux (say, #LinuxMint for simplicity) to access this functionality, since it's not AI-patrolled like the other platforms: https://flathub.org/apps/chat.delta.desktop
@eff@evacide@CNN I've quit advocating #Signal, once I learned about how most of the platforms which Signal runs on, collects (AI-driven) "Intelligence" - which can only provisionally be opted-out of, one informed user at a time.
