When TSR purchased the Realms in 1986, they acquired the right to make changes, add things, and take things away. What I say and write about the Realms is canon, unless or until they contradict or change it, in print. So, yes, they can just make the changes. ;}

Speaking from ignorance here. If Ed created the FR and what we see on the actual game differs from time to time, they can just make the changes? :o
