The value of the product is undermined by what we now know the Agencies do. Before Snowden we all thought it was an idiotic idea we'd have pervasive surveillance, now we know it happens. Before Snowden we'd buy nice to have, harmless gadgets, or use easy Google speech recognition (your reference), now we shoot them down. As an investor i'd be thinking about this kind of reaction to a product. Maybe a table-stakes feature would be privacy in a way our community had some confidence it was well thought through.
