Which days are “these days”? If it’s the past couple of years, the number is 13. That’s not most. Going back a decade, 74 out of 1,654 is also not most. Many? Sure. But most phones with USB-C are USB 2.0, and no one cares except people who don’t use iPhones but love to complain about them.
Most people are not going backwards to plug in their phones to backup data. Even those who do backup locally do so over Wi-Fi, which is now faster than USB 3. Fast, wired transfer is absolutely a necessity for professionals moving A/V data. The iPhone Pro is for them. For the rest of us, it’s not something I’d need, even if I was still doing regular local backup these days.
I see no flaw in this argument. Instead of dying, the character exists like the guy from “One” by Metallica, desperately waiting for a stiff breeze to end his existence.
