From the linked article:
How is Apple's 5% phantasy fee (aka Core Technology Fee) adding value?
I really honestly don't understand this.
I made comment years ago here. Apple runs a store. Online. They charge people to sell in it. A flat fee as a dev and then a % of sales.
Re-cap:
App store 👈
Traditionally in retail Department Store a 3rd party brand/commercial operation, say another clothes brand, would have a concession stand/stall/space on the fashion department floor, this is a step up from having the store stock your product and re-sell for you on your behalf, either way they might pay a fee or % of sales to the Department Store for that own-space which is all about their product/brand. The department store might have various ranges of it's own brand products in the various departments, inter mixed with 3rd party offerings competing in similar space.
That's all the APP store is. Apples online software store. Which they retain exclusive rights to control. The analog is well established in markets over centuries.
Take Car dealerships. Oh it's just not fair Toyota can't sell in BMW dealerships, is something I have never heard.
If you do not like the arrangement as a consumer, then you buy another phone and you get your apps elsewhere, which is available, because that is the market and the market place is very well catered for in this massive industry - APPLE is not the market. The whole argument on a facile level treats Apple as if it has an unfair advantage, like a monopoly, because it is the only phone maker and is therefore "the market". Yet it is not. It has no monopoly. It only has control within in its product range and services.
Dev / sellers can sell on at least two massive market places, across a huge range of devices, into the world market. It's a huge market. There is a lot of competition in he space globally. Other brands and have come and gone that at one point were the big players, at one pot it seemed no one could out do Nokia, and there were a lot of brands.
What is really happening is the commies can't invent things that anybody wants and so when things mature they come along and either or both, steal and try break which is really power play.
While "the market" is not perfect, people in the US sure do get the best prices on Apple products!
No one in the US pays carbon taxes.
Do people in the US want to pay carbon taxes?
