"...my bank account number changed in January, causing Apple Card autopay to fail. Then the Apple Store made a charge on the card. Less than fifteen days after that, my App Store, iCloud, Apple Music, and Apple ID accounts had all been disabled by Apple Card."
Wouldn't the same thing have happened if he didn't have an Apple Card, but instead had his credit card decline not only on their Apple subscriptions, but also the MacBook they traded in?
