The last sentence bugs me. It is ambiguous at best, but in this context it implies a criminal past. The truth is that UMG used a DMCA takedown notice to remove media that Megaupload alone owned the rights to. Megaupload felt that UMG overstepped their bounds and preceded to start said legal battle. It seems to me that the final sentence, presented without context, is editorializing; basically saying 'hey the FBI says these guys are criminals, oh and they are also in court for this other thing'.
