Damage has been done already. They will be forced to think about their privacy policy going forward. Those who have to move will do it anyway by then. I think most people like me would be have to come back. As from taking notes to business inquiries and video calling everything is mostly done on WhatsApp. I don't even think people has heard of alternatives or even uses the Volte option in the phone to make video calls. Everything is done on that one app. Soon I think WhatsApp for students or kids should come with update privacy policy and useful tools for like inbuilt notes feature, pdf reader, office tools etc.
