A leading manufacturer of dental floss brought a lawsuit against the mouthwash company demanding that the advertisement be discontinued on the grounds that it is misleading.
A. Since the dental floss company is protesting the advertisement only to protect its own economic self-interest, it cannot be seen as representing greater public health.
