Volkswagen Scandal Confirms the Dangers of Proprietary Code
There is one notable aspect to the Volkswagen emission-cheating scandal that few commentators have mentioned: It would not have happened if the software for the pollution-control equipment had been open source.
Volkswagen knew it could defraud consumers and deceive regulators precisely because its software was closed, proprietary and legally protected from outside scrutiny. Hardly anyone could readily check to see if the software was performing as claimed.
Sure, dogged investigators could laboriously compare actual car emissions to emissions in artificial regulatory tests. That’s essentially what broke open the Volkswagen scandal. But that is an expensive and problematic way to identify cheaters.
The larger question is why should a piece of software that has enormous public health and environmental implications be utterly impenetrable in the first place? A locked box invites lawless, unaccountable and sloppy corporate behavior. It assures that hardly anyone can see what’s going on. Volkswagen exploited the cover of darkness for all that it could.
