Well, the Wikipedia is by far something different from what the original intent is and with all this happy "everyone can edit" things are getting out of hand with marketers.

In this particular case, it is one thing to have an illustration of a product (say a bowl of ketchup or some fries adorned with this sauce) and a totally different thing to publish the label of a producer as a "good example".
