You can opt out of iAd data collection, per app (can you opt out once you have granted permission?). Do you know with certainty that you can opt out of the OS data collection? To be fair, the article does mention that you can disable location services for third party apps. But, again, does this mean the OS will also stop collecting and reporting? I haven't heard, one way or the other, if Apple will allow us to totally opt out, so I am withholding judgement for now.
