That seems to depend on some very specific and unusual definition of "free market economics." Usually there is some unspecified assumption of rights (particularly property rights), and actions which violate those rights are not considered to be "free market" interactions. As an obvious example, if you creep around neighborhoods looking for people with valuable property that isn't well-secured against theft, then offer to sell a homeowner the information about the security problems you've discovered, and then sell that information to professional thieves if the homeowner declines, I don't think that would be "exactly what should happen according to free market economics."
