Seems like that's the one weird trick to escape the law in the land of the free:

> McDonald's has power over decisions that can make or break a franchisee's business, such as their eligibility to renew or open new stores.

You're free to reject their prices but they're free to refuse to renew your contract. After all, what is the government going to do, force two parties to do business with each other and renew a contract? Freedom for all.
