When the flipping programmer keeps not asking me for more at and altering current art my next game will be paid. What new ad networks should I consider if using ads?
No Ads I agree, if it's paid ads are a bad idea. You can still add inapp purchases but if you include adds you will get crucified on the app store.
I don't understand the first sentence at all, but to answer your question: No, if you already get paid for building the game, then you should not use ads. If you are building the game for someone else, and they want ads in the game, then it's not up to you. Also, I don't mean to be rude, but please change the topic of this thread to "Should I have ads in my game?" - which is your actual question.
