Note that Apple could have designed it not to work this way - they didn't, they chose this more complex system because they're greedy and want 30%. This program really only benefits lifestyle businesses and businesses with like 1-6 employees. A more "honest" program would be "15% on your first million dollars per year" which would achieve the goal of helping small businesses and be simple.
Also note if your income is largely being passed on to third parties (processing transactions for charities or individual small businesses), this eats into both your margins and the profits of the companies you're passing the revenue on to. The only solution for that is for every customer to create their own developer account and upload bespoke apps for themselves - something Apple prohibits under current policies.
App Store compared to Play Store regarding discovering apps is still much worse in my opinion.
I think itβs one of the biggest gripes I have after I switched to iPhone.
Auction houses such as Christie's take up to 25% for a similar service (connecting sellers with affluent buyers), although one that's probably far easier to replicate.
*robust meaning low switching costs, but it's hard to imagine how one could have low switching costs on smart phone platforms
When you want to place an item up for auction, there are more auction houses to use than only Christie's. That might be why their price fixing scandal was discovered in 2000.
But they also get money if the software for their hardware is easy to find and browsing the App Store is a fun experience instead of getting the same "few" apps. (No wonder apps like AppRaven exist.)
If the App Store was a different company unrelated to the hardware, I think it would be a different story. But since it's all tied together, it's like their own Sales platform.
