DRM More Important Than Life or Security?

An anonymous reader writes "Ed Felten of Freedom to Tinker has an interesting writeup regarding how copyright holders are still having serious objections to the built in exceptions of the DMCA even when it might threaten lives or national security. From the article: 'One would have thought they'd make awfully sure that a DRM measure didn't threaten critical infrastructure or endanger lives, before they deployed that measure. But apparently they want to keep open the option of deploying DRM even when there are severe doubts about whether it threatens critical infrastructure and potentially endangers lives.'"
