This is false.
You don't need to give Apple a credit card to download apps. You do need an iTunes account, which can be created without a credit card (I have two with no cards attached).
If you only download free apps, you're good. You can fund the account with PayPal or gift cards if you choose to download paid apps.
Try to refrain from making stuff up in your defense of Google.
