OK even if I accept your argument, I still don’t believe that gives apple the right to stifle their competition by forcing them to jump through arbitrary hoops. Like I’ve said - they are already giving Spotify access to Siri. They just make it deliberately painful. And as a software developer I really don’t think it would be remotely difficult to route calls for music to an alternative music app. They are already doing the hard work of deciding if a request is for music or something else.

By your logic Microsoft are also fine to force everyone to use internet explorer forever because they put so many hours into making windows.

That’s an argument that was lost 20 years ago.
