Imagine being in China and finding this out after an update.

I used an iPhone a few years ago and when setting it up, I made sure to turn off all iCloud stuff. When it was time to get a new phone, I noticed all my pictures were in iCloud.

I also did not like how hard it was to try and keep Bluetooth and Wifi turned off. Regularly it would nag me to connect to an open Wifi when I was sure I switched Wifi off completely. Turns out iOS re-enables both Wifi and Bluetooth after OS updates and you can't completely switch them off from the quick settings. If users privacy was so important, wouldn't you want to make sure all that stuff would not happen?

Also, it's good practice to reboot your phone one in a while, so why isn't there a reboot option in iOS?
