Software is everywhere. You knew that already. But do you always know what that software is doing? As the recent Volkswagen ‘defeat device’ scandal has shown, when its true purpose is hidden, software can cause tremendous damage. Writing proprietary software that cheats on emissions tests goes beyond ‘cheating’ - it’s a criminal act and one that will leave the car manufacturer in reputational - and financial - ruin, not to mention the impact on customers and the wider economy. Amid the various calls for fines, resignations, and jail time for VW executives responsible for this, one point particularly stood out to us: This wouldn’t have happened if the software was Open Source.
