A couple counterarguments:
(1) "No way with the cables included in the box" is not the same as "no way." There's a USB-C to Lightning cable in the bag right next to me. That lets me plug a top of the line Apple laptop into a top of the line Apple phone. With no dongle, even.
(2) In practice, there are zero times over the last two years that I've had to plug a phone into a laptop. I can't honestly remember why I bought this cable; I think I wanted to see whether USB tethering to the phone was better than using the mobile hotspot feature (spoiler: kind of a wash). I am sure there are people reading this, possibly including you, raising their fists to the sky and screaming BUT IT IS THE PRINCIPLE OF THE MATTER, and, sure, okay, I guess. But is it?
One can make that argument that Apple should include both cables in the boxes, or a USB-A to USB-C dongle, or something. But in practice, just how many people need the USB-C cable for their phone, even if they have a USB-C laptop? The vast majority of people are probably only using Lightning cables to charge their phone from a charger, in which case it doesn't matter, or to plug into their car, which means they need USB-A anyway. (People may also be using Lightning-to-not-USB dongles, like headphone ports and HDMI output, but that's irrelevant to this.)
