There is software that lives up to these claims, it's Tinfoil Chat. The article is correct about the necessary trade-offs: due to peer to peer transport (onion hidden service 2 onion hidden service) both ends of the conversation have to be online -- it at least spools the message waiting for the recipient to appear.

For hole punching and signaling that has to be done by third party, well, the third party is TOR

TFC then goes on to break out the encryption and decryption machines from the network and passes messaging over opto-couplers to prevent your keys from getting exfiltrated. Qubes qrexec could similarly isolate the components.

The problem with these tools is that they're extremely complicated to set up and use. Grandma wants a phone number, not a v3 Tor Onion Service address.

I'm interested in usable E2EE messaging apps -- that's what I compared Converso to. Whatever this is (I will read the docs some day) is in another realm.

Definitely - adding contacts in TFC is an unreasonable burden, cannot copy paste addresses into the source machine, 56-character tor addresses have to be typed in manually, followed by the recipients' public key.
