Why implement ads on an app for kids? – Animal Fun Review

I used to love having my babies play with this app. Since I updated, it now includes freaking banner ads for automobiles. Now the can't play with this app without tapping on an ad and leaving the app. This wasn't free software, I PAID for this. I wouldn't have paid for this if I knew it was going to be ad supported. I want my money back.
