But the issue isn't that easy to understand for a lot of people. That's where Nate Silver from the NYT comes in. I think his description of the situation crystallizes this for everyone:
Imagine that you opened an Italian restaurant across the street from Mario Batali’s Lupa. It would be one thing if you merely took inspiration from Lupa’s spaghetti carbonara — if you tried to use some of the same ingredients and some of the same techniques. Maybe you’d even go so far as to track down the butcher who sells Mr. Batali his pancetta. All of this would be in the spirit, most of us would think, of good ol’ American competition.
But this is more like, when a customer orders the carbonara, sending a runner across the street to order a plate of it at Lupa, reheating it, and then maybe adding some mushrooms or snow peas. The alterations you made to the dish, whether slight or substantial, might not be all that likely to make it better: it would be hard to improve on Mr. Batali’s carbonara (if peas really made the dish yummier, wouldn’t he already have included them in the recipe?), just as it would be hard to improve on Google’s search results.
