I think the only conflict that occurs with the potential DL move is internal which would TSM be willingly taking responsibility over. Other teams are not affected so in my eyes there is no competitive advantage, in some cases disadvantage.
As a side note the only part that is questionable is how the deal came about considering the circumstances (the "poaching" aspect), which as long as it remains without proof should not be punished.
Finally, orgs. act in what they believe is their best interest, Kobbe is getting screwed and it might not even be a positive move, in the end its business. If your contract allows it, it might happen. Happened to me, can happen to anyone at anytime.
