Many people like to decide for themselves I believe; Apple can warn that it will run badly and burn through your battery faster, but if the user still wants it, they should be able to switch it on no?
Many people like to decide for themselves and then trash the product/company when it doesn't work - especially in the Apple ecosystem where they sort of guarantee the user experience will be good. While I also like to decide for myself, I understand why Apple would decide for themselves they don't want to risk that.
Yeah, I see that; it's like when people order Szechuan hotpot ultra hot and then complain it was too hot. But as I paid like 1500 euros for the device, I want the choice. They don't have to make it easy, it just has to be possible if I really want. In my opinion.
Most users don't understand those details: how many really understand all those authorisation popups? If you give too much choice to most users, they'll find it difficult to navigate. There should be an "expert" setting for those options, hiding them from the standard display.
