Apple doesn't pay them. Anyone who wants to sell media on iOS has to compete with iTunes while subject to a 30% price handicap. If that's not anticompetitive I don't know what is.
Imagine that you paid $1000 for a 1 year CostCo (iOS) membership which gives you access to CostCo but only on the condition that you live in CostCo Village, where you can only buy Certified Approved™ products from CostCo (which have a 30% markup) and if you choose to leave, you'll lose everything you bought while you were there. Home, furniture, electronics, everything. CostCo Village is a nice place to live and the products sure are nice but imagine 50% of the population living like this. From a consumer perspective it's shitty because you have no choice and from a vendor perspective it's shitty because you either play ball or lose out on half the population.
Sure there are Sam's Club (Android) Villages where you can still buy from other chains or independent grocers but it's just stupid that you have to make this choice.
Another thought...we live in a capitalist society (assuming you live in the US). With the customer base that Costco has, you can’t realistically expect them to give away the most valuable thing they have to vendors, can you? Sure if you run a single convenience store you can’t charge for shelf space, but if you run 1000 of them you probably can. So if you’re Microsoft for example, you need to beg developers to build apps for your mobile OS because the value proposition i.e. paying users just aren’t there. Flip that story on its head and you have Apple.
Also, I don’t quite understand what you mean in your last point....
Realistically there’s no way to buy digital video without also fucking yourself into a walled garden that restricts your use of your own licensed content. There is no real competition there for the experience people want—video they can play on whatever they want to, whenever.
And yea, a DVD is in the dame league, but it’s a format that deteriorates with age. Not exactly an investment format like vinyl. At least you can back up MP3s and play them with any software you like.
Isn't that a choice Google and Amazon make because they don't want to pay Apple's fees for sales going through their marketplace? If that's the case, it doesn't seem anticompetitive, since everyone is charged the same fees no matter what. Google and Amazon just don't want to pay it.
Same thing as the Kindle Store, you can't buy Kindle books through the Amazon app but you can buy them through the browser. Because if you buy them through the app, Apple takes a cut, but they don't through the browser. So Amazon made the choice to not sell books through their app, even though many other merchants sell digital goods through their apps and pay Apple the fee.
