It's trivial to change retailer, not so changing which app-store you use, especially not on Apple hardware.
I can't buy a Tesla, Tiffanys etc at any other place except their retail store.
You can goto any city on this planet and find hundreds of small third party stores who will repair it. Everything from cracked screen, new case, battery replacement etc.
In the case of Apples App Store, you can't change store without a significant cost in both time and money. You literally have to buy a non-Apple phone to be able to change retailer. Potentially also having to leave behind significant already paid for products, both hardware and software.
These are things inside one store, as in Spotify and Apple Music are both for sale in the one store, and while Apple takes a cut, which could force Spotify to increase their price, they do have full pricing autonomy.
I’m not entirely against the fact that Apple has a walled garden in the form of the App Store, just because they do seem to invest in keeping a certain standard of quality unlike Google, but I’d say that’s a separate issue.
And Spotify probably doesn’t want to be in the store business anyways even if Apple allowed it, Epic Games is probably the first major case I heard of a company doing similar on Android (where it’s allowed) and almost immediately they opened a security vulnerability into everyone’s phones so...
I read that comment as regarding similarities between two different apps that stream music, and two different brands of the same product in a store.
The store the two brands are in isn't really relevant past the fact the same company that that owns the store owns one of the brands, and certainly the nature of the store doesn't affect the comparison.
If they thought that having multiple stores was important to them they would use Android.
Nobody is going into the phone purchasing process blind.
What most people do understand is based on experience in the physical world, where expectations of fair pricing is reasonable, because when you can select whatever store you want, that is an expected effect.
No, but maybe they chose Apple because on Android their lockscreen got taken over by the top result for flashlight which is actually malware (something that happened to a family member and drove me to recommend Apple)
Also what kind of strange victim blaming is this? You want to know why they got a flashlight app instead of knowing why the top Play Store result is malware?
