If you maintain the USB-A, users will keep using it instead of switching to the superior alternative and driving progress.
I want a world of one universal connector and/or no wires/cords. USB-C is the start of this future.
I'd find the "Apple is doing this for our own good with a single unified connector standard" position more credible if the new iPhone used USB-C.
Sadly, almost everything is still USB-A. USB sticks, 2FA tokens, mechanical keyboards, mice, and - oh yeah - iPhone charging cables.
Would I like to move to USB-C? Sure. But as a professional, there's going to be some situations where I need that backwards compatibility, if not for me then for some client. There's going to be a really long transition period, because all that USB-A stuff is still 100% functional.
And if you argue that adapters are the solution, then clearly we still need at least 1 port, so why not leave it? Design is supposed to improve usability. Technology is always a compromise, but for many people, thickness wasn't an issue in the first place.
(BTW, magsafe power cords don't need orientating. Kind of a solved problem)

This argument is backwards. If it's superior, then people will switch. For many use cases, USB-C offers no practical benefit - in other words, it's a solution to a problem that doesn't exist.
Is one USB-A port too much to ask for, for the sake of backwards compatibility and potential emergency use? On the other hand, ironically people (including me) would pay $$$ for a USB-C iPhone. That application of USB-C is clearly superior!
Why are you selling the option of having ONLY USB-C or ONLY USB-A as a binary thing?
