The issue with WhatsApp is that it never had a sustainable business model. First it was free with the hope of monetizing. Then it was free for a year, but a buck afterwards (pretty good if you ask me). Then WhatsApp found many users could partake of the e-economy due to lacking debit&#x2F;credit cards, so it went back to free with some idea of Corporate relationships paying for things.
