I would categorize it more as wear and tear rather than disposability, but I do agree that the nature of repairing a MacBook is only for a market that can afford it. It’s much like repairing a car, either you continue repairing it, or you drive it to the ground and buy a new one.

As a software developer, I personally do find MacBooks to be more conducive to my profession (my current MacBook is approaching 10 years), so while I wouldn’t say I agree with “more people need to leave it”, I would say that we as customers should pick the product that suits our needs the most (apple or otherwise). Which I believe is the original message in your comment (get the product that you can afford and are in the market for).
