The tightness of hardware integration isn't a bug, it's genuinely a feature; In fact, it's the defining feature that makes Apple hardware great. Socketed RAM, CPU, and Storage just weren't worth the tradeoffs, namely size, weight, cost, and performance. Including those modular interfaces just wasn't worth it when the internal interfaces would be obsolete within 5 years, and the average user was replacing sub-components 0 times over the life of the device.
The user being able to swap parts easily is _neat_ but it's just not an required feature, any more than the user of a car being able to easily hot-swap the engine. The right level of integration provides a tradeoff the maximizes reliability, cost, performance, and repair. A professional can still replace almost any component of a modern laptop, with a few thousand $ of specialized tools, and the battery, the only component with a fixed lifetime, can be easily replaced at home.
I really hope Framework can continue to develop hardware with documented repairability, without falling for the myth that tight integration and quality are mutually exclusive.
