I don't want to explain why OnePlus has their ordering the way they do. It has more to do with production power than being elitist or exclusive feeling. Ive explained it more than a handful of times. Motorola isn't the Motorola of old. They do not have the production power to meet demand much like OnePlus has.
We can go back and forth all we want, but the constant will always be Motorola not producing enough and any more strain will cause problems. Right now Motorola will not be able to handle another potential 5M+ orders. If they could there wouldn't be OoS everywhere or a backorder 2 month or so long.
Apple numbers are astronomical yet even they have trouble producing units to meet demand on all carriers with the production power they have.
