It strikes me that people concerned with the risk of being charged for committing a crime like this are probably exactly who Apple is trying to deter with this messaging. For all other employees, it serves as a reminder that this stuff actually happens, to be on the lookout for it, and that Apple will protect the hard work they've done with their full legal might should someone try to do something like this.
