Why is that you'd demand this of _Apple_? Doesn't Linux and the plethora of devices it supports give you this already?
I ask as a willful customer who prefers the complete control Apple provides. I never have to think about "porn" or "bitcoin scam" or "upsells from parent's bank" or any other crap from being easily accessible on my kids' or elderly parent's devices. Even Steam has some arcane filters that eventually allow porn content to be visible in the store. Honestly, outsourcing the basic policing of content to a company like Apple is a feature; not a bug.
Besides, there's so many competing devices that give you all the freedom + control you want out there already. Right? What am I missing?
Now, I admit, this means I'm under the mercy of what _Apple_ thinks is "right" or "wrong". As an extreme example, I'd also like to disable _all_ non-vegetarian content from my kids' or parent's phones; to appeal to their "religious"/"moral" beliefs. But obviously that's a not a PoV upheld by the App Store. Similarly, I can empathize there are many other viewpoints people hold that may or may not be aligned with App Store guidelines.
But despite all that, why can't Linux devices serve the "control my devices" need.
