The DOJ release today is made up of "recycled allegations" that don't point to criminal copyright infringement. The Megaupload conversations are about whether cloud storage users are doing bad things on the site. At best, the conversations allege secondary copyright infringement (where the DOJ is trying to hold Megaupload responsible for the infringing acts of cloud storage users), and the U.S. Congress has not yet created a criminal statute against secondary copyright infringement.
