I don't blame TNA for this at all. Truth be told, it would be fucking stupid of them not to go through with it if Kurt Angle wanted it so bad himself. This is huge, this is "Monday night wars" huge. The wrestling world hasn't felt anything like this since Vince McMahon bought WCW and ECW.
If you want to call anyone stupid, place all of that blame on Kurt Angle. Sure, I think it's stupid of him to do this right now, but it's happened and so be it. I'm willing to go along for the ride, for better or for worse.
