I guess I don't see this as "right to repair". I think this attached to the importance of the enterprise sales channel. They can pilot this with consumers, but the value here is in allowing the fortune 500 to adopt apple devices and staff for same-day repairs. They just announced and MDM, and they have rolled out the ability for iOS apps to run on m1 macs. To me, this makes it look like apple is vying to become the standard app dev environment for new enterprise apps, and have that inertia drag their devices into businesses. These small changes they've announced all seem to be stacking in that direction.

edit to add: Security focus and end-to-end control are what the Apple ecosystem is built on. If the results of the trial with Epic go poorly for them, they still have all these features that make their ecosystem a good choice for paranoid/security conscious enterprises. If they get enough of those on the platform, then they have lots of companies depending on that security to back them up when Apple highlights their walled garden approach as a feature.
