Re: The rationale is "[fewer] chargers
How much waste did Apple create when they switched from dock to lightning?
Also, consider the wider aspects of this move, rather than just the immediate ones. Yes, in the short term it'll mean anyone upgrading from an older to newer iPhone will have to get a new cable/adapter and maybe replace some accessories, but those are all one-time hits. Longer term, once those Apple users are set up for USB-C operation, it allows them to intwract more freely with whatever other devices they've got which are also using USB-C, reducing the likelihood of needing to buy more cables etc in future.
