Stealing Intellectual Property

The food company Sharwood's make a big thing in their advertising about travelling the world to find recipes that they can bring us in their products.

Now am I missing something? If they take a recipe that has been shown to them and they don't pay a royalty then isn't that stealing?

If they modify the recipe then they should state that they have done this and not claim that the recipe is authentic.

We get hot under the collar about child labour. We should do the same in this instance.
