Huh, first I’ve seen that writeup. First in-depth well-reasoned set of criticisms I’ve read on the XMPP+OMEMO setup, which is my goto and usual recommendation (and what I still find most power-efficient on a degoogled phone, most usable and reliable despite its stagnation).

Gives a good overview of the accumulated technical debt/chaos beneath the surface. Really hope that conversations and omemo can sort out their mess, or that other clients like kaidan can rise up and push omemo forward, because xmpp itself has been a solid foundation.
