People are complaining in the iTunes Customer Reviews about the ads, not necessarily because they're there -- advertisements already adorned the Angry Birds HD level-selection screen. However, now if you want to try a level again, when you pause and start over on that level, the "Rovio News" ads show up, slowing down your quest for the coveted three eggs on that particular level.
Adding advertising to free apps seems justified, but slipping the ads into this $5 Angry Birds HD app somehow crosses a certain line. You've paid your $5, so you should be allowed to escape all those ads for Angry Birds merchandise.
Lets be fair, though -- you get a tremendous amount of gameplay for your $5. It's just that we were getting that gameplay without the ads before, and now it feels like something has been taken away. Will Rovio remove the ads, or wait for the firestorm to die down?
