No, signal sucks because its UI/UX sucks and no amount of explanation or persuasion makes normies want to use it instead of TG/WhatsApp/FB etc.

actually I agree. I literally forced my relatives to switch to signal. other people when you tell them telegram is a piece of shit say "why not" or "I have nothing to hide" ) I tell them - what if I find (а если найду )
I really don’t think Signal is that far off on the UX side tbh. SimpleX has that problem though.
