> If Coca Cola pays for all the shelf-space in all the leading supermarkets, how is society ever going to experience my super-cola made from unicorn tears and sun-drops?
Who cares? Antitrust doesn't exists to protect companies, it exists to protect consumers.
Cola is just a flavor of soda, which is just a type of drink, and can be easily interchangeable with an enormous number of drinks: water, juices, teas, etc.
As long as Coke's actions are not stopping competition in that larger market with the result of harming consumers, why should anyone care?
