This is why they need more economists and fewer lawyers. Game theory tells you that that technique will not work against a population that is as cohesive as students are. We force these little buggers to associate with one another every day. All it takes is one geek per school to break the code, and the good copy leaks out through the school instead of over the Internet. All they are doing is increasing the economic value of geeks, enabling them to get more dates (a noble undertaking, actually).
While the economists were there explaining this to the lawyers, they could also explain what it means that the delivered cost of a listened-to song is asymptotically approaching zero, at a time when their clients' business model turns on the relatively costly physical distribution of solid-matter goods which are really just glorified containers for that which is to be delivered.
The fun part about telling lawyers stuff like that is that they don't have the slightest idea what you're talking about. So they will continue to accept fees and burn the money from the glorified box-makers... for engaging in activities that fight the Invisible Hand.
