I am entirely happy with App Store rules that prevent apps spying on users, as a fallback for OS-level security measures, or accessing files that weren’t specifically shared with the app’s user (in iOS, each app runs as a separate Unix user). If the OS is written properly, that wouldn’t be necessary (though for economic reasons no useable OS is) and they could use other methods (IIRC most countries appear to accept the FSF’s assertion that linking to a library is creating a derivative work that needs a copyright licence).But there is a 'common good' of trying to save people from self inflicted injuries to themselves and people they interact with. Some call it the 'nanny state', but the wreckage of not supporting people dealing with technology clogs up so many other public services such as the courts, law enforcement, and can leave people busted and unable to recover.
My mother was preyed upon by evil people on the internet. Keeping her safe was a tough road for quite a bit. Having Apple's focus on saving the user largely from themselves was such a priceless feature. Protecting her phone from the leagues of sketchy people out on the internet to the degree they did was such an amazing valued feature. Apple saved her from total personal destruction, saved her from exposing her life to people that seek to destroy it for any profit they could get from it, or worse, just the glee in it all.
What I object to is apple’s use of content-based restrictions on apps, and their gpl-incompatible App Store rules.
My reason for not switching to android is that android has more spyware baked into it, and has worse hardware support.
