The problem isn’t setting prices in response to market conditions, it’s colluding with other companies to raise prices in unison. That’s what makes something a cartel and that’s what happened here. And I don’t mean raising prices because you saw that someone else did, this was literal phone calls and texts about when prices should go up.
I mean, given a lot of the rhetoric that happens around egg prices, it does seem like setting prices in response to market conditions is a problem to many.
