These kids aren't currently, and never have been, under contract. You are worried about ND shafting Wake Forest, but from Hartman's perspective, his future has greater potential at ND. In this case, you are arguing that the desires of the institution are greater than the prosperity of the individual.
I don't believe any of this is good for the future of CFB, but at this point, there is no absolute moral good or bad related to tampering until pay for play enters the equation.
Even if we were to assume that Tommy intitiated the Hartman recruitment, that falls well short of ND selling it's soul.
