The longer rant is here[1]. In short, it's because Apple is unique in its hatred of third-party repair and they are trying to gain a monopoly over repair of their devices. This is not normal, it's actually very abnormal if you compare it to how repair industries normally work for electronic or mechanical components.
The problem is not that Louis (and the rest of the right-to-repair movement) want them to go out of their way to be accommodating. They want them to follow how the rest of the repair industry operates, and to stop going out of their way to make repairs more difficult. Louis has a very strong personality, but he does actually have a point.
Economics is an excuse, especially since we know the Apple explicitly has spent money on trying to thwart third-party repair shops. The automotive industry went through this song and dance in 2012 (before the 90s it was the norm). All they want is the ability to purchase legitimate chips from wherever Apple sources them and have access to the same schematics their technicians have access to. They're not asking Apple to become a wholesale supplier of repair parts.
