In all the years I've been using Apple products (Mac, iPhone and iPad), I've never felt "constrained" to the platform or what choices I have with software. I have everything I need to do my job, pursue my hobbies, and play the odd game (though for the more demanding stuff, I use an Xbox One X).
I've terminated by Epic Games and Spotify accounts because of their actions. I believe this coalition is talking completely out of their arse. 30% is not an unreasonable sum of money for the services Apple providers for developers. My only two complaints are:
1) Game streaming from the likes of Project xCloud and Stadia. Apple's decision seems a bit bonkers and impractical. Yet I kind of understand where they're coming from.
2) If a film or TV distributor removes a title from your local country iTunes Store, and you haven't backed it up (which you can only back up the SD or HD version of a title - you can't back up the 4K or any extras which come with it), you won't get any recourse from Apple. Which is bad for the Apple TV platform, quite honestly (and if you have a massive iTunes movie library, does Apple really expect you to back the whole lot up?). If a developer misbehaves like Epic, is Apple responsible for any and all refunds, or will Apple direct you to Epic (who will direct you back to Apple)?
I don't want the iOS/iPadOS platform to be opened up. My iPhone contains sensitive data about me, and if opening up iOS to the point where 3rd party developers can just stuff any old crap on it without Apple checking and filtering, it could lead to all sorts of nefarious things. Is Epic, Spotify and the whingers that follow them prepared to take the responsibility for that? I don't think so. Apple won't do it for free.
Video streaming is a whole different ball game with its own rules. If I've understood it, to qualify your app needs to integrate AirPlay/AirPlay 2 or some other Apple-related feature in order to qualify for the 15% cut and to be able to charge outside of the App Store payment system. I think that's been misinterpreted by a lot of these companies that are complaining about Apple. (This policy looks to have been introduced around the time Apple TV app came on the scene - see

In any event, a big fat raspberry to Epic Games, Spotify and the rest of the "coalition".
