I look at it a little differently. Apple doesn’t owe anyone, anything. There wasn’t any sort of guarantee, regardless of the time you placed that order, that you/anyone was entitled to launch day delivery.
I was in the 9/25 crowd and less than 12 hours later got notification that I was bumped to 9/19. Was I happy, yes, but it wouldn’t have mattered either way.
Look, every year people place orders, get certain dates and end up having them bumped up. Pretty common that Apple under promises and over delivers in many cases.
I would bet that people with 9/25 date will have their phone on 9/19.
Just offering a different perspective.
