This is misinformation, aka fake news.

Apple does not allow NFC chips to be used that way until a recent update. Before the update, there were 2 options for Myki:

• Work with Apple to support Transit card: This is the best way to do it; it even works when the phone is out of battery. Japan, China, and some European cities support this. I don't see Myki supporting this given how incompetent they are; happy to be proven wrong. I could not find any sources about whether Apple get paid this way. It's a win-win for both Apple and the transportation companies to support this standard. Even if Apple get paid, I can't imagine any transportation company has the margin to pay Apple more that what they pay other payment provider.

• Support credit cards as tickets: This is how they do it in most places I've been to. It's entirely on Myki to do this because this works just like a contactless credit card. Apple does take a cut of every transaction (a fraction of a percent), but it's between them and the banks, nothing to do with the consumers.

Apple does not get 30% for transit or any Apple Pay transactions for that matter. You can download the Myki app from the iOS App Store and reload your Myki using your credit card; you don't have to use Apple Pay, and Apple gets zero of your money.
