Agree I would have rather just had faster Lightning than USB-C
Lightning with USB 3.0 has existed since 2015 and was only ever used in some iPad Pro models. Apple has since switched to USB-C for newer iPads. Even back then they didn't provide Lightning to USB 3.0 cables if I remember correctly, they only released an adapter.
Lightning has IMO stagnated; it isn't going anywhere.
I'm all for Apple going USB-C even though I like the lightning connectors solid feel more, but for politicians to decide what ports a device have to use to get power is a slippery slope that risks holding back innovation.
There are ample technical standards and requirements that products must fulfil before they can be sold in the EU. This is not different. Technology changes all the time, so do technical standards and regulations. The USB-C requirement is not set in stone, the European Commission was also given delegated powers to change the technical specifications and the product categories to which they apply.
The USB-C port is also just required for powering the device. It has great versatility also for data transfers, as proven by USB, Thunderbolt and DisplayPort, which Lightning most certainly has not.
