The sticking point here is that iOS users could always just open a browser tab and interact with patreon.com as a webpage - and iOS developers were systematically blocked from even informing their users that it was an option. When Apple breaks the rules and perjures themselves to the court, it's gonna be an uphill push for them to argue that they deserve to get paid for doing no work to produce, deliver, or maintain the digital content that's at issue here.
I feel like it's being framed as if Apple was solely responsible for delivering digital content. They aren't. They provide app package downloads in a "safe and secure" manner through the app store, and justifiably charge a fee for doing so. They incur real, actual costs in doing so and provide an actual utility to developers AND customers. Once that app is downloaded, it's no longer Apple's problem to keep it running - that's on the developer's side of their shared responsibility model. If Apple isn't responsible for it or incurring the costs, WHY are the entitled to arbitrary add-on fees?
And one step further, if your position is that they are entitled in the iOS ecosystem, why aren't they also entitled to do so on MacOS platforms and Microsoft entitled to charge a platform "rake" fee for every peice of business conducted on a Windows machine?
Should I be responsible for cutting MS a check for a quarter of my closing costs on my new home in a couple days, because I'm doing the transaction on a PC that Microsoft has spent time securing the OS on?
