Advertising sucks. It turns would probably have been an enjoyable half hour into annoyance. And for what? You as the developer aren't even getting paid for this particular advert, or do you really think plastering the whole thing with banner ads gets you more appstore downloads. Well here is one iPad owning gamer who's turned off by it and who may have checked it out on that platform if you had just left it in the description or in the loading screen. Let me know, but don't get in my way. It's a fine line in some cases, but this is way passed that.
