That's why a per usage pricing would be fairer. And yes, the app having one thousand $10 purchases would pay way more than the app having a single $10000 purchase, but that's the point.

And working with Visa doesn't stop you from offering Mastercard or Paypal or others. Apple mandates you use them.
It's capped in the EU - 0.3% for credit card, 0.2% for debit ones. That fee includes all the risks of chargebacks and fraud processing.
