This is just one way information goes from being private to being public. It is sensible that people who provide intelligence to the market be compensated, whether they're better at inferring/predicting or whether they just know something we don't.

Obviously, in a case like this, an individual would be violating the terms of their employment/non-disclosure agreement. I agree that is bad!

I don't think that damns the concept of "predicting known information".
