I'll play the (intentional) Devil's Advocate here to present an alternative viewpoint. I like iOS, but not Android. Let me explain why. I personally love Linux, Unix philosophy (I'm even sometimes an old beardy zealot about POSIX standards and the old way ), and inherent customization possibilities. On the other hand, I don't want to manage my phone like a desktop or laptop computer, or a server because of a plethora…
I agree with you overall, but felt the need of commenting as I thought "Settings do not change spontaneously" was true as well but it is not! I just discovered the other day that you cannot turn off WiFi or Bluetooth. If you do try to disable either of them, they will be turned off but only for a day. The next day they enable themselves automatically. So much for not changing settings by themselves :)
If that isn’t what you want to happen, you go to the Settings app and turn off those toggles. (But I wish they would have a matching statement on screen that clarifies their changes are permanent until you change them again.)
Temporary toggles being in the control center is great. Most of the time that I quickly disconnect from WiFi or Bluetooth, it’s to solve some immediate, temporary issue.
The settings aren’t “changing themselves” — they’re doing what you asked them to do. The written message tells you what you asked them to do in order to teach new users what these buttons do.
