Vince McMahon is terrified of letting anyone go to TNA, which is why there has been tremendous heat on guys like Carlito for interviews that they've done and few are ever fired (though Carlito is doing jobs left and right, and Orton is almost certainly doing the job Sunday). The Kurt Angle situation was different because WWE didn't think there was any chance of him going to TNA and were actually terrified that he was going to die under their watch in the very, very near future. There isn't that fear with him Orton.
