A) Information is not Soda, it's not an arbitrary choice
B) Soda is also a physical distribution business - Coke and Pepsi dominate physical distribution, shelf space etc. - these problems don't really exist in news, or rather, in totally different ways.
So - 1) they are different kinds of 'products' in terms of their civil relation (i.e. we don't care about gossip information), and 2) the businesses are actually different.
