I think Apple knows its customers really well, and caters to them in a way that winds up feeling exclusionary to a lot of folks that have a hard preference for Android for mobile, or Linux or Windows for PC. Apple builds products and makes designs that meet the needs and wants of the people that use their products, and they do it very well. What an enthusiast might gripe about is a convenience for many others.
I think of it like features in a car, like traction control. Max Verstappen might prefer no traction control because he can control the car better without it, but Becky down the street doesn’t have that skill so having the feature on automatically is the better design, because there’s only one Max but thousands of Beckys. Max has the alternative of going out and buying a race car or sports car that meets his needs, but it doesn’t really make sense for him to removed about how much Becky’s car sucks because it automatically turns on traction control.
WiFi is automatically on, and only paused from control center, because it’s a better experience for most of Apple’s users. Almost all use-cases are that the user wants to turn WiFi off temporarily, but having it turn fully off makes it so that it’s more likely for the user to forget to turn it back on and burn their mobile data. Most of us have had that experience. But, since Apple rolled out that feature, it hasn’t happened to me, which I see as a better user experience. I understand that’s not what many others want, and that’s fine. It just tells me iOS isn’t for them.
