Apple won't let third parties produce Apple compatible parts (or sell parts sold to Apple also to non-Apple repair centers). Even if Apple just got out of the way, and offered no help/supply chain, it would be a stark improvement. But instead they've been using hardware DRM to effectively make third party repairs impossible. If you replace a part with an identical part, you need Apple's software to authorize the change otherwise it won't boot.
