Be interesting to compare with how prevalent the different ad types actually are, how effective they are, and how much money they typically cost. Preroll video may be more "annoying" than Related Links ad units, but they also pay a LOT more and are probably more effective any way you measure it.
Speaking as a developer. You may be paid by the impressions but how much you are paid depends on the CTRs. Nothing works for CTRs like targeting. The more data you can share about users, the better it is for you. All this other stuff probably contributes to user churn as much it does to your bottom line. This is one of the reasons that a lot of apps ask you for location permissions even when they don't need it.
