I don't think you're arguing from a good place - specific concerns have been called out about pretty specific design flaws from Apple. Instantly upgrading those criticisms to a full generalization about all components in the phone doesn't feel particularly constructive.

Do I think that Apple shouldn't use some proprietary thermal paste to mount their heatsinks? I don't really care and I don't think anyone here does either - but the tools to get general access to the device body are a different matter... they're necessary for a wide range of relatively simple repair operations.
