This is a classic case of "apparently someone didn't get the memo."
"The Fairness Act (also referred to as the Consumer Review Freedom Act, an identical version originally passed by the Senate) effectively voids any retail customer agreement clause that seeks to penalize the customer for publishing — or speaking — honest feedback. It also allows the Federal Trade Commission and state attorneys general to go after companies that continue to try to quiet or punish customers with these sorts of clauses."
