The purpose of a system is what it does.
Apple obviously has a perverse incentive here. If people can't repair it then they buy a new one. They can always come up with an excuse but it doesn't carry much weight when they're so weak. You can't replace the SSD or easily replace the battery in a Macbook Pro on the theory that it would make it heavier or thicker. Framework proves this is bullocks by making laptops where you can and they aren't meaningfully heavier or thicker.
They make them unrepairable because they intend to.
