A Star of a Reality TV Show About People Living

A star of a reality TV show about people living with addictions likes to wear clothing from a particular brand; this includes T-shirts with the logo of the brand prominently displayed. This brand sues the TV show over the use of their logo on the show. Why do they want to stop a reality TV actor from displaying their logo?

A) They do not want people with addictions to serve as a reference group for people considering their brand.
B) They do not want the TV show to make a claim later that they should have paid for product placement (when a company places their product in a television show, movie, video game, etc.) .
C) Out of respect for viewers, they do not want to expose people to their product if those people are not seeking it out.
D) They fear that excessive exposure may increase the popularity of the product beyond what they are able to supply to retailers; they don't want to create a demand that they cannot meet.
