Seems like everyone is doing this now... Sonicare, Norelco... I get the cost cutting + simplifying international packaging aspect. Just pass it on to customers. At least Apple has the other excuse that users might prefer wireless charging, so if users already have that or need to go out and buy it, the included charger just gets thrown in a drawer if it ever makes it out of the box.
A masterstroke of corporate gaslighting for their disposable product.
