Got an example of them making deals "on my behalf" part?
I mean, Apple doesn't get great deals on manufacturing prices or memory chips, and pass the savings onto us. Instead, they do things like charge us for little memory increments and keep the extra profit for themselves. Tens of billions of extra profit.
Apple could've used the fees from OUR Apple Pay purchases to give us some nice rewards kickbacks, like at least the banks and merchants often do. But again, Apple wanted it all for themselves. For doing nothing during the purchase.
Is their insistence on wanting Amazon and others to pay for selling in-app movies from non-Apple servers, something done on our behalf? Nope. They want money for, again, doing nothing except gating access to iPhone owners.
Was Apple's e-book price fixing done on our behalf? No, it was done to benefit Apple.
Apple tends to be a greedy bully when they're in a strong position. It's part of the legacy Jobs left.
Why do you think the App Store is so profitable? Precisely because it is so hard to pirate apps in ios, so users have have buy an app the old fashioned way by actually paying for it. This means that apps are more profitable for developers, which in turn incentivizes them to continue developing for ios. The end result is a wider selection of high quality apps for me.
As for the e-book saga, think about the ramifications of lower prices for books. How many people do you think will stay around and continue publishing the books you love to read if they didn't think they could earn a fair wage off it. You want good stuff, you have to be prepared to pay for it, and that's precisely what Apple is doing here.
What's good for me as the consumer isn't always about getting away with paying as little as you can, but about ensuring a win-win-win proposition for everyone involved.
The lack of bloatware on my iPhone and Apple's ability to push software updates through whenever they feel like it is another example of how Apple's negotiating clout has benefited me as the end user. None of this "Verizon blocks Google wallet because they wanted to promote their own mobile payments standard instead" or me finding that my carrier has already subscribed me to a dozen paid services on my behalf crap.
As for Apple Pay, what Apple is doing is adding an extra layer of security to the transaction, from touch-ID to the Secure Element, while ensuring that my data stays with Apple instead of the merchant. That's the value add, and if Apple didn't have the clout of its hundreds of millions of users backing it, the other merchants and stakeholders would never have capitulated.
I am a paying customer of Apple, which means that Apple's interests are fairly well-aligned with my own, which is to afford me a great user experience. In short, I want things done the Apple way, not anyone else's, because these other companies have not demonstrated that they care as much about my user experience as a customer, or that they are willing to go the distance that Apple has. And sometimes, if I have to suffer in the short run to benefit in the long term (Apple Pay only came to my country in the middle of this year, but I was willing to wait), I will wait.
Apple has earned my trust, my faith and my patience.
