I feel for Spotify and other companies on the 30% tax but I also love knowing that any purchase by my family or myself is protected, private and easily refunded if there's a mistake. There are already a lot of apps preying on kids but it would be at another level without the in-house payment system. I think something like 30% on the first purchase and then 5-6% for any recurring purchases would make more sense. I kno…
This is a ridiculous stance. Essentially it's the same as saying that you're scared to pay for anything online and you only trust Apple for making online payments. There are other solutions to feel secure about paying online or via an app. For instance, if the app asks you for payment, you could be first shown its rating in the store, if it's low.

I'm not particularly scared of paying for things online. I'm scared of almost anyone else in my extended family doing so, though. If you think that concern's "ridiculous" you haven't watched them use the Web. And lots of them—especially the older ones—have (rightly!) never entirely gotten over fear of buying things online. Some(!) of them do buy things online, but reluctantly, with great deliberation. In an app on an Apple device? Concerns gone. Even for me, that little background stress of being on alert for shenanigans quiets down when I'm in the Apple ecosystem. Far lower (though non-zero—there's a reason I do almost no iOS gaming) permitted rates of douchebaggery is one of the things keeping me on iOS, and the one-source-of-payments is a vital part of that.
[EDIT] there are further benefits to users and developers alike, I should add, when the UI for a purchase is the same in every app. It's worth 30% to "defect" from that, so worth it on the individual level, but if it's permitted at all then the game's up and everyone loses.
