This. We're thinking about the cable in terms of charging which is it's primary use, but it's not the only use case. There are people who will want to be able to do wired transfers of files. I know syncing phones with computers via a cable seems old hat, but when you've got 100GB worth of ProRes video files, made capable by the new iPhone 13 Pro Max, having the Lightning cable there just creates a massive disconnect between the phones capabilities and it's wired connectivity. Especially video editors using ProRes.Good luck getting large video files out of your fresh new iPhone pro max. Lighting in 2021 is an embarrassment, it’s hardly better than micro USB.
In the interest of staying on topic though, although I do have a pro USB-C outlook I think Apple should be able to do this if they want to and not due to dictatorship from the EU.
