Dear Apple, please stop restricting this feature from iPhones!
For a long time, all iPhones sold in China have had the ability to prevent specific apps from accessing WiFi and cellular data. You can toggle it on or off for each app individually in the settings. This is not only good for blocking ads but also preventing apps (that don't require internet) from stealing your data.
This feature is embedded into iOS but Apple chooses to disable it in everywhere but China. This is a purely anti-consumer move.
Please bring this feature to ALL iPhones!
