Apple doesn't have to spend their time discussing with you about legal dispute among copyright holders. If anything, you are lucky that they don't ban the developers who posted the app in the first place. I wouldn't mind a policy that said: "if you ever get us in a copyright dispute, you are banned forever from our store"

Instead, Apple was told that the app had a copyright problem, and it took them 2 months to take it down. Yes, it's slow, but no, they are not evil in doing so.
