They had usb 3.0 speeds over lightning on some models (e.g. the iPad Pro), but they kept introducing models that were usb 2.0 speed only for no apparent reason other than cost savings on the rest.
And they still do it with USB-C. iPhone 16 and 16 Plus are restricted to USB 2.0 speeds; you have to shell out for 16 Pro or 16 Pro Max to get USB 3.0.
I don't think it's about cost savings, even. It's just a way to differentiate the products, Apple-style.
I’m not a huge fan of the EU government making specific demands of specific companies to adopt specific technologies, but this is Wi-Fi and telecom tech has a long history of adoption through legislation. So it’s not at all unprecedented and is probably the lesser evil in this case.
