A lot of questions have been raised by the recent “dieselgate” scandal. Should automakers be held accountable for ethically questionable actions? Are emissions standards in the United States too restrictive? Are we ever going to stop appending “gate” onto every mildly controversial news story? But, for Hackaday readers, the biggest question is most likely “how did they get away with it?” The answer is probably because of a law a lot of hackers are already familiar with: the DMCA.

How could they get away with this simple trick when a brief look at the ECU software would have revealed it? Because, they were able to hide under the umbrella of the DMCA. The ECU software is, of course, not intended to be user-accessible, which means that Volkswagen is allowed to lock it down. That, in turn, means that the EPA isn’t allowed to circumvent that security without violating the DMCA and potentially breaking the law. This kept the EPA’s hands tied, and Volkswagen protected.
