False advertising is a civil dispute between two competing businesses. You can only sue for false advertising to recoup monetary loses caused by a competitor’s false claims. As an example, you own a pizza shop and make 30” pizzas. The guy across the street who makes 20” pizzas puts up a sign that says “We have the biggest pizzas in town.” You can sue and prove they used a false claim to gain a competitive advantage. That’s what false advertising is. You as an individual or consumer can’t do shit about it.
