Users are people, not cattle. Yes there's value in sensible defaults but once you've paid (dearly) for hardware, you should be able to use it as you see fit.
A cow using an internet connected device is better at avoiding scams and malware than my parents. At least the cow won't have the dexterity to click on garbage. My parents will never have sufficient knowledge of modern English nor the concepts around what is and isn't malware.
For them, I need a device that lets them Facetime and WhatsApp and browse the internet and takes photos and videos of their grandkids. They are never going to create anything, and iOS is perfect for them.
