You are missing the point. When faced with a broken device and a very high Apple repair bill (have you see how much they charge for things like new keyboards, screens and batteries?) many people will just throw the device away and buy a new one.
Only if they are stupid. Instead of throwing the device away and buying a new one, they can return the broken device to Apple for an "out of warranty repair", which means Apple takes the old device and hands over a "refurbished" device, which in practice often is brand new. The price is usually about half the price of a brand new device.
