Speaking of reading is good, did you read it? It gives you references to cases that have supported both sides of the argument. So how is it not addressed by any court rulings when it gives examples of such court rulings? One section mentions Suntrust v. Houghton Mifflin Co. which supports a creative work, in this case a parody, of gone with the wind. Another section mentions Anderson v. Stallone where Stallone actually won against an author who wrote a proposed Rocky IV script.
So please, again, tell me where it's not addressed?
Oh, and I like how you condemned me for "Cherry picking" and then do the same thing to my post. Way to have double standards.
