Depending upon how you look at it, there is more than one competitor to Apple. It kinda sucks that most of the competition to iOS runs one operating system, yet that one operating system is supported by multiple hardware vendors and multiple online storefronts.
Yet there is also another competitor to Apple on iOS devices. It is called the web. Patreon in no way owes money to Apple if the end user fires up a web browser on their phone and makes their contribution through the website. Argue all that you want about convenience, and you're probably right on that front, but it is a way to circumvent Apple to have more of your contribution delivered to the intended recipient.
In the end, the decision of iOS users to support Apple's practices are at issue here. Sometimes you just have to say no using whatever means are at your disposal.
