Apple knew iOS7 was going to be "polarizing" before they announced it, and they're used to heavy criticism after keynotes. It was the centerpiece of their second-biggest yearly public announcement. It's being shown off on the iOS7 website. The iOS7 theme is here to stay; Apple has already introduced it to the world. Yes, they will tweak details through the beta process of course (that's what betas are for), but overall it will look the same. Get used to it.
