Bundling absolutely is coercion. Apple makes some of, if not the best mobile hardware in the world. It would definitely be reasonable to purchase Apple hardware and run third-party software on it, just like on Macintosh. It would also be reasonable to run iOS on alternative hardware. Neither of those scenarios is possible today because Apple uses the compelling nature of individual aspects to force consumers to accept the entirety of their ecosystem.
No, it's not. There's no use of force or threats. Just like if I have a backyard BBQ, you come over, and I say you can't bring your friend because I don't like him. Just don't come to my BBQ.
