Crazy. So they're explicitly selling crippled devices to most of the world.

Many Chinese users actually hate this feature because of how it's designed. There's a mandatory pop-up upon the first launch of every app to ask for your choice, which can be clumsy if you're setting up a new device. If you tap the wrong option (which is common since the dialog is small and crowded), you have to go deep into system settings to restore internet access. Moreover, many foreign app developers know nothing of this and have their apps throw an error even before a Chinese user has the chance to give permission, forcing them to manually kill and reopen the app to be online, adding to the errands.

What? Why is this Chinese market only? This is exactly what I wanted. There are Apps I simply don't want them to touch internet.

Its Chinese market only because of regulation. China mandates it. Don't implement it = you don't get to sell in China.

If Apple wanted to provide this willingly they would. That its only available in China due to government regulation tells you all you need to know.

i got an old EU market redmi (yes im broke) and you can turn off either wifi or cellular or both for any non system app. remember apple had to put in work to actively block the feature outside of china.
