You imply that Apple is too greedy and stupid to actually want to take people's money today, instead,
building up a false narrative of shortages and constraints with an eye to actively delaying sales.
The truth is that there are in fact shortages and constraints, hence demand exceeds supply, especially for the Jet Black models. This has happened every frickin year, and Apple's part of that "hype" is that they give you a two hour release of new products. The rest is media and individuals, and this year, the media meme was that few were interested in the iPhone 7, because bland or something, and most tech savvy individuals went along with that.
Evidently, consumers disagree with the pundits, and I'd argue they are preordering in massive numbers, as always. Apple will not be publishing figures, so you'll have to rely on 3rd parties to figure out sales.
Here's a metric regarding "hype"
