Sure, I will buy another phone and all the apps I paid for in 15 years of usage. It's very trivial and simple.
I invested money in the ecosystem and now there's vendor lock-in, I'm bound to it unless the usage becomes so unbearable that the pain to change vendors is less than continuing the one I have, the pain threshold only grows for each passing year I'm invested in the ecosystem. Do you comprehend that?
Opening a phone for others to develop apps on top does not encroach anywhere into Apple's sale of phones, it just creates a massive wall to guard against other competitors selling apps to their platform. They charge for the phone, and now they extract rent from something they sold through the App Store. Please, think deeper about this, you are missing the point entirely.
> Like I said in another comment, if Spotify is not happy with Apple they can manufacture their own device and sell to consumers.
No, they can't. That's not their business, they don't have the capital to develop and foster a whole 3rd platform of devices + OS just to move away from Apple's ecosystem, that's the whole point of developing a platform: creating a massive lever against competition because of network effects. Network effects are very hard to break from, hence why most major tech companies try to leverage that (look at Meta/Facebook, they are shit but still it's very hard to compete against due to their size).
> People buy and use Apple devices of their own free will, and developers develop for their devices of their own free will as well. And there is plenty of competition in the market.
There's only 1 competitor in the market: Android, manufacturers using Android are not 1 competitor each since none of them are providing a full platform, the platform is Android on top of some devices.
Free will is a massive naïvete to throw here. Is there free will when there are no other options to reach a market? Is there free will for online sellers in the USA to not put their products on Amazon since you'll be living on the outskirts of the market without any meaningful way to penetrate into it if other competitors have an advantage simply by paying the Amazon tax and selling their products through Amazon?
I think you are too naïve and ideological, that blinds you from understanding market forces and markets in general.
