I think the biggest privacy / free speech issue is sustainability. Or the OpenSSL / OpenPGP problem. What's a feasible monetization / business model look like built around software that is privacy-focused and customer-centric? Because it's all well and good when you have a massive social data-mining company to bankroll your development, but what happens if that disappears / priorities change / the US government leans hard on FB? Sustainability is important in code development too. PS: In no way is this intended to diminish the efforts of the team. Hats off to everyone at WhatsApp for implementing this, FB for supporting it, and EFF for their general awesomeness!
