Just one example of the arbitrariness of anti-trust law. In the US soft drink market, Dr Pepper is usually considered a cola, it has a flavor similar to colas, and it has caffeine. However, for anti-trust purposes, it’s not considered “cola”, it’s considered a “pepper-flavored” drink, a category where Dr Pepper wields considerable market share, despite Dr Pepper’s significantly smaller share of the soft drink market overall. When was the last time you saw 7Up (another Dr Pepper brand, lemon-like flavored) available on a fountain or vending machine in place of Sprite (Coca-Cola’s lemon-lime) or Sierra Mist (Pepsi’s more conventional lemon-lime)?
