Touch grass people.
In my experience, 9 times out of 10 what this actually means is that they just don't know it's an issue! The type of person who would be confused by, say, the iOS control center, is not necessarily the type of person who would easily identify and raise the issue of it being difficult to do something on their device. They would just be mildly annoyed that they can't figure it out, or that the device "can't do it", and move on to find some other way. You may not realize it if you don't interact with those types of people but they fundamentally do not think like you or I do and what may be an obvious problem-solving process to you (e.g. identify a problem, figure out what tools are at your disposal and whether each could be helpful, check for functionality that could do what you are wanting, ask for help from others if you can't figure it out on your own, etc.) may actually not always be so obvious.
That's why the main way I find out people don't know how to do something is from them seeing me do it with my device and going "what!! I didn't know it could do that!!"
Other than that, Apple tends to lean a little elitist in certain areas, when they actually slightly over-estimate the competence of the average user. A lot of their thinking makes perfect sense to me now, but I am not an average user by any means, and even me in a wrong mindset could not make sense of it in the past.
This happens a lot on the Mac, where a lot of, say keyboard shortcuts, are just kinda there and no guide walks you through them, and no help page or documentation entry mentions them - you are just expected to learn and grow how you make use of them over time, from menu bar entries, the internet, or other operators directly.
It doesn't fit everyone, but Apple is one of the world's only havens for a very particular type of crazy, and that is exactly what Steve Jobs was all about.
