it goes beyond repairability though – look how much apple upcharges for SSD and RAM.

The majority of their profit margin comes from overpriced DRAM and flash storage:

RAM:

  - 16GB -> 32GB: +$400 (+$75 retail)
  - 16GB -> 64GB: +$800 (+$200 retail)

SSD:

  - 512GB -> 1TB: +$200  (+$40 retail)
  - 512GB -> 2TB: +$600  (+$150 retail)
  - 512GB -> 4TB: +$1200 (+$350 retail)

Since you can't upgrade it yourself, buyers are paying more at point of purchase, and a high end machine depreciates significantly more over time. With something like framework, you can buy a base model and upgrade it as needed, and resell value of all models is higher because they can easily be repaired and upgraded.
