That seems disingenuous. Yes there is no explicit switch that prevents the user being informed about updates ever again, but there are no forced updates that I'm aware of. If you don't want to update, don't.

It is not possible to block downloads of updates or to switch of daily update reminders on new iOS devices. This is a well known problem: http://osxdaily.com/2016/01/04/stop-ios-software-update-noti...

The only option is to avoid Wifi or configure your wifi router to block Apple.
