Really.
Again, not my problem. I am paying for payment processing. I don't care if Apple wants to hire 50 engineers to wash their toilets with the money and then want to make a Superbowl commercial of the video they made of these 50 engineers, my money is going to payment processing.
As such, the 30% is plainly, only, for processing my payment. This is what I as a paying customer of In-App Purchases am getting for my money (30% of the price of the purchases in my app).
Explain to me how I, as a customer of In-App Purchasing (namely a developer who's app uses this service) am not paying the 30% nor have I anything to do with it ?
Are you confusing the term customer here with the end-user ? The customer of In-App Purchases is clearly the developer. Are you confused ?
I get that Android is also overpriced then. Paypal/Visa/Mastercard are much cheaper. However, you know what ? Android's In-App Billing is completely optional, so that's not a problem. If I want to host my application on the Android Market but use my own payment processor instead of Google's In-App Billing, I absolutely am free to do so. No restrictions, no pricing rules, no "if you link to your site you have to pay us 30% of every transaction!" nonsense.
Come on. You get it now ?
Frankly, I really don't understand you, or the same people who keep asking.
Also you're making it confusing - are you asking as developer or as a user. Work with me. As a regular app buyer (aka user) you're not paying for 30%. Of course as a developer you're paying the 30% to Apple. Did I really need to spell that out?
Bottom Line: whatever the 30% is used for, that's the cost to play. You're paying for the privilege to play. If you want to make money in their store you have pay them a percent, just like any store (digital or physical). Why is that so hard to understand?! It's in all business. And it is your problem, as you have to pay it. If you don't want to make money than don't develop apps to be offered in iOS. Come on man.
We're having a pointless discussion. You need to do research. You obviously haven't, as I suggested. Didn't you see Marksman with the words "MacRumors Analyst" in his sig? He basically stated the people weren't using business sense. I think you'd consider his input to have weight.
Comparing it to credit cards is confusing. It's similar, but different at the same time. It's not the same industry and not the exact same business model. I'm not going into it, as it could take forever to explain. Also I'm not a banking expert. But I do know the tech, telecom, and cable business models. You're just saying it's the same because they both have the label "transaction fee." Go study it.
And it seems your wrong about Android from my research. You say that there are "no restrictions, no pricing rules." Well from my just going to the dev site it says in-app transactions still have a 30% fee. I posted the quote earlier. So I'm not sure what you are talking about.
Again, I really don't get you. Go find a friend who really knows business. Have a discussion. Ask them these questions. Maybe after a good discussion you'll see it a bit differently. But if you choose not to see things, then you won't. I've learnt a lot on these forums. Things that I've thought I was right about, but I wasn't. I've gone and researched and studied this. I kept an open mind. Give it try.
