Good! Time to move to telegram! And delete your facebook account! And uninstall whatsapp! I expect nothing less from HN.
Telegram's encryption is not end-to-end unless you opt into "Secret Chats"[1] and many claim their crypto is not secure[2,3] as they rolled their own[4].
The latest Google chat app Allo also backed away from defaulting to end-to-end encryption for all messages as it lessens the quality of their auto-assistant[5].
The Axolotl protocol (developed by Moxie and Trevor[6]) is available in Signal and was later adopted by WhatsApp. Signal has far fewer features than other chat applications, and people aren't clamoring much about it; I would guess because many people place features > crypto.
Wire (wire.com) uses this protocol as well[7].
WhatsApp being part of Facebook has already called into question their handling of privacy[8], the feature they were originally advertising as their main strength.
