I don’t see why that matters. Outside health and safety or merchantability, do we really want anyone dictating what features software can or cannot have, and how they may or may not be implemented? There is no requirement on Apple, or any other manufacturer to have an App Store at all, or to facilitate the installation of software from potentially competing firms, or any regulations requiring how they may or may not go about doing it. It’s not obvious to me that’s a route we really need to go down.
