I don’t disagree tbh.
However, in terms of ui/ux it is still the closest comparison that’s not wholly dominated by capital drives. Things like WhatsApp have better ui, but I don’t think anyone remotely interested in things like signal would use those at all if not forced to it.
Right now, matrix, arcane chat, xmpp, and similar options are better than signal under the hood (supposedly, I don’t have the knowledge base to verify for myself), but the ui is anywhere from outdated to outright horrible.
Besides your list? Matrix via element or elementX. I’ve been test driving arcane chat, which is decent enough, but too new to be widely used enough to really say much.
