If I understand correctly, it’s still not great for repair shops because the parts are expensive enough that you can’t really make any money and because you can only get the parts on demand (i.e. you can’t buy parts to just have on hand). That and the pain in the ass time wasting process you have to go through to pair the serialized parts through an Apple specialist once the repair is done.

This is only really targeting individuals who want to repair their own devices, but even then, it’s priced such that you’re usually better off just having Apple do it themselves.

I doubt it.

Apple is famous for not keeping extra inventory around and all the tooling for building parts for older devices is probably long gone/repurposed.

At best, you’ll probably only start seeing replacement parts for new devices moving forward.

Most repair professionals lobbying for right to repair actually acknowledge that and are totally fine with Apple making things more complex as a trade off for a sleeker device. Microsoldering is a skill people pay good money for. Funny enough, Apple is making things a bit easier to repair now (e.g. removal tape on laptop batteries) as it got even too hard for them to handle repairs themselves.

What third party repair professionals aren’t okay with is Apple purposely not providing board schematics, making deals with chip manufacturers to ensure that nobody can buy certain chips on the boards for repairs, and serializing parts ensuring certain things can never be replaced properly without Apple’s servers blessing it (e.g. screens, batteries, etc).

The idea is you should own your device you fully paid for and should have the right to fix it.
