On the one hand, this isn't surprising. An plain description of how the ad market works demonstrates why - one way of looking at it is a mechanism to run your code on random peoples' machines.

On the other, policing, controlling and maintaining healthy markets is a primary government function. When the cops are afraid to look at a market for fear it will interfere with their jobs, that strikes me as a government failure reinforcing a market failure rather than attempting to fix it.
