Actually, Sandy, this may be a smart move on the part of Nikon. There are a ton of 3rd party batteries for various gadgets, laptops and cameras out there, some of which have burned, or otherwise failed catastrophically.
(Here's an article from How-Geek about the dangers of 3rd party batteries. It speaks mainly to batteries for laptops and phones, but one could easily extrapolate this to any gear that uses batteries.)
So, I really don't think Nikon would want someone to sue them, and also, I don't think a photographer would want his/her camera to self-destruct in their hands (possibly) causing injury.
I always buy OEM batteries. Yes, they are more expensive, but if it does fail and ruins a gadget or camera, I have a stronger case for repair or replacement of the item.
