The first part is always true, but criticism still serves as a disincentive even when the person doesn't stop using the product. There are plenty of cases where a person believes it's in their best interest to use a product, yet still criticizes it because some aspects of the product are hostile to them. It would be most effective to stop using the product, but sometimes, the criticism alone makes a difference. I disagree with the parent comment's statement (that a person should agree with the company's practices if the person uses their product). Disagreeing with hostile practices is better than agreeing to them, even if the person continues to use the product.
