It would be absurd to expect Apple not to be influenced by the rest of the industry, but the scale of the similarities by Android (compare pre- and post-iPhone Android) and especially Samsung (the Galaxy S with TouchWiz was essentially a 3GS clone) is much more than just skin deep.

While iOS 7 may look more like WP and Android, anyone who uses it can tell it still feels and works like iOS. Apple harp on about how design is more than how it looks, and it especially applies in this case as it doesn't work anything like Android or WP. But use a Samsung Galaxy S, and you can immediately tell that their apps menu is a wholesale ripoff of the iPhone's Springboard with next to no effort put into differentiating or improving the original design.
