That "free" money comes from fees paid by the seller to the credit card company, and is passed along to you in the form of higher prices. Unfortunately, paying cash seldom lets you opt out of these credit card driven price increases.

That last part is what makes "free" vs. "well not actually free" functionally identical.
When you pay off the card, it can automatically debit the Apple Cash account first. Basically all my purchases are 1% cheaper on that card than my other ones. Sure, spending $9,900 instead of $10,000 doesn’t sound like much, but it’s painless free money.
