> E2EE, especially for group chats, is _the_ reason to use Matrix. It's an extremely hard problem, and you'll basically need to replicate what Matrix does if you want to solve it. I would be inclined to call this FUD. XMPP had E2EE before Signal and Matrix even were released. Current XMPP uses a flavour of double ratchet encryption (OMEMO) that puts it in par with those two, while working on MLS (just like Matrix). > And forget about mobile apps, XMPP just sucks on mobile. And yet, Conversations uses a fraction of the energy and resources Element requires. And does audio/video calls more reliably. And works well for 1:1 to large chat groups with thousands of participants.
