The DMCA's language is something like "circumventing an effective technological restriction," but I don't think "effective" really gets much juice. Like, despite the total brokenness of DVD CSS by now, it's still going to be "effective." On the other hand "circumvention" sweeps up conduct that just bypasses DRM rather than actually breaking it.

Edit: for accuracy, it's "circumvent a technological measure that effectively controls access" to a copyrighted work.
