Taking liberty to concoct a scenario. If Walmart asked shoppers to take a photograph of the product layout on display at their favorite shop (which say happens to be Target because its the most popular in town) and used that to make small modifications to its own layout, would you say Walmart needs to credit Target, or that its copying Target? This is an arrangement between Walmart and its shoppers and there is nothing Target can do about it other than making a brouhaha. I don't see why things have to be different in the digital world. We all know how user interfaces historically have been blatantly ripped off.
