And here is where your entire argument breaks down. In software for anything BUT iOS if you want to self publish and distribute you can keep all that money. You have the choice in what disturber/ publisher you want.The iPhone is Apple's product that uses its own hardware and software. They have spent billions on developing the product, the App Store, developer APIs and marketing.
What right does anyone, including governments, have to say Apple how Apple does business, I don't hear customers complaining, it is companies like Spotify and Epic games that are complaining, because they have to pay commission on sales to Apple for using the App Store.
If Apple had not created the App Store they would not have made the profits that have done off Apple.
I have worked in the computer software industry for 30+ years and we had to give a minimum of 30% discount to resellers to sell our software. If we went through a large distributer it could be up to 60%.
Even if Apple had reduced their commission to say 10% the likes of Spotify and Epic would have still complained.
Well if you dont like paying commission to Apple stick to Android where you still have to pay commission and a larger market.
If iOs was on all the phone manufactures phone's then I could understand the complaints as they then would have have been another Microsoft in the respect of a monopoly.
I for one will not use third party stores, I want Apple's security.
The underlying issue is for iOS the ONLY option is to threw Apple and pay those fees. The App store is not the problem, being require to use the App store along with some very heavy handed greed control by Apple is the issue.
Most developer yeah will gladly use Apple but there are a lot that dont want it or dont have a need to pay the fees.
If you want to go by your argument then where is my former employers cut for the 10,000's of iPad companies bought only to use my former employers software. They did not care about iOS just they wanted to use the software from my former employer and the only thing that ran on it was you guess it my former employers software. Apple made out great on that deal. I also know if they could self publish they would of because the App store provide them nothing.
The rest of their software for desktop they just self published and self hosted.
