Exactly. This is outrageous. The only decent chat app these days is Telegram, really. Even they still want you to use your phone to log in (but only once). But I guess that's the way it is for now.

Frankly, I hope those apps will all be gone and forgotten in favor of an actual open sourced, widely used protocol. Or maybe they'd incorporate one. But in any case, I think it's a shame that when email is decentralized, chatting is not.
