I think this is the most important to me. On Android, this is only the second app that is likely to have a large userbase and e2e encryption for chats. The fact that its opt-in is a non issue to me.
Didn't know WhatsApp had default e2e encryption. Might install it and check it out. I imagine it sends some sort of personal information back to the facebook mothership, though.
