Given that Apple has no data recovery service for any of their products (even if you tell them that you'll give them a limitless pile of cash) and that they solder storage into most of their devices (that is paired to the CPU -- so you cannot remove the flash chip and put it onto a working board to recover data), this is a very bold claim.
Maybe you don't need your phone to be repaired when it is water damaged and you can no longer get photos of your children (that you should've backed up, but didn't). Maybe you want to pay US$300 to replace an out-of-warranty phone when the only thing wrong with it is that a headphone jack got stuck inside the port[1]. Maybe you don't want to pay more than the device is worth to fix a brand-new device[2].
Apple devices aren't just hard to repair, Apple as a company is anti-repair -- and defending this practice is not a reasonable position to hold. I understand arguing that Apple products are easier to use, or that they are more consumer-friendly, or that consumers shouldn't have full control over their devices because they'll probably brick them, and so on. But arguing that them being irreparable is a good thing is not justifiable (even if you don't need your device repaired, someone else will, and out-right ignoring that is misinformed).
