To support your public commitment to privacy: OTR or better for WhatsApp, and/or a third party client so we could do this, please. I'll excuse the metadata issues for a while if you build the app in such a way that confidentiality is protected independent of your infrastructure, and if pushing a "bad" app to clients is detectable. It's still a pain if targeted malware is pushed to individual clients, as those clients are unlikely to detect it. There are some emerging ways to address that, but first things first. You have literally billions of dollars; it would take at most millions to implement this. Making an app with 450 million uses around the world somewhat more secure would be supremely meaningful, even if it's not perfect.
