Because we're 'commitment to the environment'. I feel Apple very openly insults our intelligence more and more these days. So it'll save the environment when we buy a USB-C charger in another box - possibly with worse packaging?
So is it possible its' just greed and bigger profit margins Apple? Just be honest.
Not defending anyone here , but thats not the logical POV , if NO ONE has a charger , then sure you are right , but most ppl have chargers aplenty , for me what goes bad is usually the cords , they get thrown around and getting damaged , the power bricks never broke on me so I have tons of them through the years.
