Google is doing fine.
You're right. They can run the App Store how they want, but in the U.S. antitrust laws come into play here.
Three questions though for conversation that requires you to think more from legal perspective and less of who has rights or what not.
1) A possible problem with this is that developers do not see much data getting passed to them per transaction. So really how much of a relationship is it with the developer compared to the customer? Apple obviously gets way more of the customer data than the developer gets. Is it a relationship with the developer or the customer?
Developers get the money.
Customers get the app.
Apple gets everything else (data, their cut of the profits)
I suppose an argument can be made that consumers are Apple’s customers as well, not just developers. I am not sure if that is enough to make a case allowing consumers to directly sue Apple though.
But your point has its merit.
2) Some apps have stores and don't suffer the Apple tax. An example is the Amazon app. But why is it only digital goods are charged the mandatory 30% and not physical goods?
Because Apple can.
I argued in my earlier response that I don’t think Apple is justified in doing so, but it is certainly within their power.
3) Why does Apple insist on disallowing other digital app stores to exist in their App Store? Although I understand Apple has the right to do this and this would enable other companies to side skirt around the 30% potentially, isn't this inherently by definition anti-competitive?
My take is that the Apple experience is defined by Apple having total and absolute control over every aspect of their platform. This, amongst other things, includes app developers having to capitulate to whatever demands Apple makes, inane as they may sound.
As a consumer, I shouldn’t need to decide whether to purchase my app directly from the App Store or from a third party. I see the merit behind there being just one source, and my decision is either “buy or don’t buy”.
Would other app stores have to abide by the same rules as the ios App Store? If yes, then what’s the point?
If anything, I would like to see Apple actually enforce their App Store rules and policies better on the big boys. Like using some of their leverage to force companies like Facebook and google to optimise their apps better for ios devices, respect privacy settings better and include the newer APIs like PIP mode for YouTube.
Else, what’s the point of all that leverage if you are only going to use that power to bully the small fry?
