N1b not having encrypted messages by default (and only for 1:1 conversations via very hidden secret messages functionality) destroys all usability for me. I can't trust a "private" family group chat that is out there for everyone to read, no matter what company is behind it.
Thanks a lot for your perspective, I agree with you. I have seen a trend of switching from WhatsApp to Telegram in my friend circle and after all I am not sure this changes anything for me, as both WhatsApp and Telegram are using closed-source encryption by default. As you pointed out, at least WhatsApp promises that it uses end-to-end encryption.
