Re: Do what I've done
Researched; iOS 9 nags you to update to newer iOS 9s a lot more than pre-9 nags. That's probably the reason for the disparity in anecdotes.
That being said, "Apple are far worse for this kind of crap" is still patently false. Microsoft has sent the update as automatically approved, has promoted it from 'optional' to 'recommended' within its update classification system, offered prompts with only 'upgrade now' or 'upgrade later' as options, and has started prompting users whose administrators have used the official Microsoft tools to prevent that. And unlike iOS, Windows offers no official way to delete the update once it has been silently downloaded.
Hits for '"ios 9" nag': 77,200. Hits for '"windows 10" nag': 148,000.
