Hiding behind a mystery
I always pay for apps if an app has a paid version that does nothing but get rid of ads. I do like to support developers, but if they don't offer an ad free paid version I still don't want ads in my apps. I never click on ads if I do see them so they don't generate any money from me due to ads anyways....
Devs get ads per view as well. I forget the amounts but if you're screen is on and you're playing angry bird for 10 minutes, each ad that runs by generate $0.01 for the dev. If you click on it, they get additional pennies.
