Once Carpathia decides to delete/sell/get rid of the data the case will be dropped. The US government only has to keep this tied up in court until Carpathia (which legally could delete the data) deletes the data. Once the evidence is gone they can easily escape from this horrible mess they have created. "Your honour, I have some bad news. Since Carpathia has deleted the data we no longer have a plausable way to continue with this case."

Megaupload destroyed, goverment doesn't have to pay them anything (after all it was Carpathias fault) etc.

They can't just drop the case because mega upload is an email blast away from being full on running again. Users don't have to resign up, reupload data or anything. That is why the data needs to be destroyed, which I believe is the end goal of the United States Government.
