How about the very existence of the OGL and GSL? They didn't have to do the OGL with 3E. They didn't have to have the GSL with 4E, they could have just closed it up.
What other major gaming company offers a royalty-free license to allow other publishers to use their trademark? Heck, when Green Ronin started licensing True20, they charged a fee.
If the original GSL is "absoulte" hostile, why is it being used by some companies?
Where does all this anger come from? Between justanobody and carmachu, you'd think WotC ran over their kittens or something.
