Monitoring phone calls seems like a big leap from where the conversation was it. I think most people would agree that if you keep things private that even a private entity shouldn't expose that. But if you broadcast the information publicly, then you are now liable to be held to a different standard. So if a group started holding advertising public WhatsApp calls where they'd discuss plans to exterminate minority groups then I think WhatsApp would be OK in canceling their account (assuming its consistent with their TOS). I don't think messaging apps should be able to collude though. This should be at a case by case, company by company basis.
