Each cartel member sends commercially sensitive data - supply costs, pricing, sales figures - to Potatotrac, and then Potatotrac uses that data to give "advice" to the cartel members about "optimal pricing."
This is just price-fixing, with an app. The fact that they don't sit around a table and openly discuss pricing doesn't make this price-fixing. What's more, they *admit it*. A director at McCain said that "higher ups" forbade anyone in the company from competing on price.
