Apple said it was the exact same tools their repair technicians use, and offered all the tools for a $49 rental (which, honestly, probably doesn't even cover shipping for 77 lbs. of equipment). The Verge, iFixit, Ars Technica, and others claimed Apple deliberately designed and priced their repair program to make self-service repair not worth it, even if there wasn't the part serialization.
Which... what malarkey. Of course repairs are cheaper when you don't need to rent the toolkit every time and can reuse tools. According to Apple, the parts are the same cost the Apple Stores and their repair partners get, and according to congressional testimony this is not a profitable program, so what do you expect? Apple to sell parts publicly for cheaper than they get themselves? Do you want Apple to send you the repair tools for free and have cheaper parts? That's what they were saying - the parts should be cheaper and the tools should be less complicated even though that is what Apple literally uses. You think Apple repairs screens with guitar picks and are upset Apple doesn't ship those instead? It was really disappointing.
Imagine if Apple was a car company. They wanted the ability to repair their cars, so Apple agreed to loan them for $249 hundreds of pounds of equipment for repairing just about anything on their cars. Then imagine if people cried this made car repair too complicated by design. Right to Repair does not encompass right to simple, idiot-proof, no-tools repair.
