You are making the bold assumption that piracy is predominantly tied to affordability. The example of rampant music piracy transitioning to digital music sales proves that piracy is often disassociated with economics. Many people who pirated Photoshop could have easily afforded it, but piracy was chosen because the option to pay nothing was available and convenient.

As for justifications, you've completely misunderstood my point. I'm not claiming that Apple should justify its 30% on piracy. Let me put it another way. I reject the assertion that an alternative universe where the iOS marketplace wasn't a walled garden would have reliably resulted in higher overall revenues for developers.

Obviously, if you wanted to propose a situation where everything was exactly the same but Apple took a smaller share of revenue, developers would make more revenue. But for most developers this hypothetical is now real, since all but the largest developers can now receive 85% of gross revenues.

There is one area where I disagree with Apple's policies, which is how they only allow in-app purchasing for multiplatform "reader" content. Companies like Netflix and Spotify should be allowed to subscribe customers using their own merchant system within their app, so long as the subscription is entirely multiplatform "reader" content.

The reason why I disagree with Apple on the above is because it's simply too dangerous to stand this ground. If Apple wants to be in the business of selling music and television, they need to suck it up and compete on a level field. Their current stance looks too much like penalties for Spotify and Netflix as protectionism for Apple Music and Apple TV+.
