The formatting seems to have gotten messed up. Let me try again:
> the bill require repair shops to possess a third-party technical certification
This puts the choice of whether independent repair shops should be able to repair devices entirely in Microsoft's hands, for no apparent reason. I also wouldn't be surprised if Microsoft required involved parties to sign an NDA restricting their ability to talk about Microsoft, which is exactly what Apple is doing.
> and that manufacturers be required to provide the public only the same parts and documents that their authorized repair providers already receive
So if a laptop's glass is cracked, but the authorized repair providers only provide complete LCD assemblies, then the customer has to pay for the whole LCD assembly with all of its layers instead of just a single pane of glass.
Similarly, if an authorized repair provider chooses to provide the battery and the motherboard as a single unit, which is already a thing, then a customer wanting to replace their battery has to pay for the whole unit and the labor costs associated with dismantling an entire laptop.
