Ads?? Why are ads in this BOUGHT app? – Plants vs. Zombies Review

First off, great app. Love the game play, art, and SFX. I bought this app long ago for the first or second gen iPod touch before EA bought Pop Cap. I've downloaded the game again and this update brings an ad at start up! Why?! I've already paid for it. EA should stop double dipping into people's pockets!
