Apples margin gains in the guise of being environmentally friendly is clever marketing. Almost making the consumer feel guilty if they feel cheated. What?? You don’t care about the environment!? Then doubling down on it and charging 20 bucks for the power adapter.
Foxconn reports of environmental impact have been less than stellar, so there’s that too.
But to your point yes probably Johnny and others who left Apple likely did have a stronger emphasis on consumer experience.
For Apple it‘s simply a win-win. They save a little money and the environmental impact is smaller. You can call it “marketing“, but the fact of the matter is that 95% (or so) of all consumers that buy a new iPhone in 2020 just don‘t need another USB charger. Let alone a humongous plastic box for their new Watch. Another fact is that Apple is doing more and more (and more than most) to become environmentally friendly, something that just was not as much of a widely recognized problem/task when Jobs and Ive called the shots. To me personally, it considerably adds to the „consumer experience“ when I unpack a new product and feel like the packaging is as minimal as possible.
