I must disagree strongly. For one, there was no need to indicate that any more nuanced arguments had been given at any point, since the argument of "hacking is illegal" is already completely and inarguably inacceptable. This is for the following reasons:

The word hacking was carefully chosen as means of emotional manipulation (see: https://www.google.de/search?q=hacker&tbm=isch ) and is used profusely in the document, mirroring the manner by which the advertisement industry burns brands into the collective memory. The excuse of it standing in for an activity defined as "modify the video game’s access controls" is only given in a footnote, instead as a glaring bold definition, which is intended to hide the fact that the word was redefined. Further, the redefinition itself is laughable since there already exists a solid term for that act: http://en.wikipedia.org/wiki/Software_cracking

There may be further arguments in the document, but it is fairly obvious that they are not the primary payload and are only present to fulfill legal requirements and provide a hull on which the primary payload is carried.

Edit: In short: If you read this document only as a legal document instead of the piece of advertisement aimed at manipulating human emotions it is, you miss the true nuance. And that is what the EFF was crudely pointing out.
