To be honest, this move by Apple is good for first world countries where many people may keep their older devices and power adapters, but will raise the costs in other countries where people usually sell their phones (with accessories) and replace those with new ones. Oh wait, people in first world countries do trade-ins too.
I think a minuscule number of people won’t mind this. For the rest, these phones are going to cost more than before with the additional purchase of adapters.
