How is it a worse experience? It's ridiculously simple: The app sends a public key to the person you're talking to. The end user doesn't even need to notice it. What am I missing here?
Signal isn't nice to use on multiple devices. I'd lose my chats if I lost my phone without backing up the keys. Actually WhatsApp somehow deleted my chats even though I restored my phone from backup, idk. Signal also stops notifying you if it goes out of date.
It's fine for the use case they're meant for. Unlike Instagram, they had these usability limitations from the start, and they delegated auth completely to the phone providers.
It's not terrible. It's just worse in some areas. Which is of course a worthwhile trade-off for many people. Just... Some people don't really care about the privacy part
I used to help a nonprofit with their facebook account, made it a real pain in the ass for everyone involved.
Of course facebook has no customer service and their slop docs were of no use.
