Using an opt-out is completely different from using third party ad blocking technology and is much more friendly. I can set the IDFA opt-out on my father's iPhone and nothing will break, but if I set him up with ublock or dns blocking and it starts breaking websites, he will be totally confused and not recognize what's happening. Also, using hacks to block tracking is not 100% reliable and allowing the user to have a specific option like Apple does is better for the user.
