More specifically they don’t make “parts” available but “parts assemblies” - a large collection of parts attached together. Replacing one part requires buying ones you do not need and replacement is merely a fallback when you can’t actually repair the part. To repair a part you need it’s parts (e.g. a chip on a circuit board).

Ah, so this is effectively identical to Apple’s approach to repairability.

Yep. If your USB port breaks, they want you to replace the entire motherboard for a thousand bucks.

In other words, they took the Apple approach to right to repair. Disappointing but not unexpected. This is the same company that got rid of their “don’t be evil” motto after all.
