Google would be insane to not offer some version of end-to-end encryption in a chat app in 2016, when all of its biggest competitors have it enabled by default.
Who are all of its biggest competitors? Messenger sure doesn't do this (does it even have E2E at all?), Skype doesn't, either. Telegram, even if you considered it a big competitor, did they finally enable E2E by default? Or do you still have to open a "secure chat" for e2e? Kakao, WeChat, ... who else?
Honestly, aside from WhatsApp, I can't even think of one which anybody would consider "big".
That's indefensibly different from "All".
EDIT: Cool, I just learned iMessage is encrypted e2e! That's "Two" :)
