Unless iTunes shuts down the Netflix app they will be selectively permitting one of their vendors to blatantly violate their Terms of Service which explicitly states that anyone that attempts to circumvent Apple's ability to profit from subscription services within their store will have their apps removed.
I'm curious if there's any legal restriction on a company deciding selectively who they enforce their terms on and whom they don't.
