<i>> Anonymous end-to-end encrypted</i><p>End to end encryption implies that you have established an encrypted connection with a known participant and secured it by verifying your keys either off-band or via some CA provider to prevent MitM attack.<p>If your chat partner is anonymous, and your only connection is via offered service, there is no way to determine if you are being spoofed.<p>So anonymous end-to-end encryption is an oxymoron. I wish people would drop this e2ee fetish, insisting it everywhere, and would learn how it works, so they would be using the real thing where it makes sense, instead of opting for readily supplied snake oil.
