The Wired article mentions that "Universal did not challenge Stephanie Lenz's assertion that the video was a "fair use" of Prince's song."

This is correct. The judge's decision mentions that Lenz claimed fair use. It would have been remiss of him not to mention a challenge to that claim, if there had been one. It's neither necessary nor customary for a decision to mention everything that hadn't been claimed.
