I must admit, the ability to sway stock prices is pretty far from what I worry about when I think of bad ethics in press, but it does happen to be the kind of thing that would make licensing prone to corruption. The money influencing that kind of corruption would be right at the door of the licensing body, just waiting for the first person to crack the door open.
