What is there to "live under"? You can already buy 3rd party parts, nobody is stopping this.

If Apple started bricking devices if they didn't have authentic parts in them... yeah, sure, I can see you point. But they don't, and you're free to repair devices yourself or take them to a repair shop who does this for you.

Frankly I don't see how this is particularly different from Samsung or any other android manufacturer, besides maybe aftermarket parts won't warn you that they're possibly not authentic.
