Let's say I own a lemon orchid and it's known around the area people are welcome to come pick a few as they want, but we primarily sell wholesale. One day, John down the road (who doesn't own an orchid$ decides he wants to sell lemons wholesale too. He proceeds to recruit pickers and they start combing through my open orchid stripping trees to sell.
As a reaction to this behaviour - which I clearly didn't intend for, but did technically allow - am I being anti-competitive? Would you classify this as "shutting down a competitors business"?
