Censorship: The act of hiding, removing, altering or destroying copies of art or writing so that general public access to it is partially or completely limited
Boycott: To protest by refusing to purchase from someone, or otherwise do business with them
So if a movie theatre refuses to show an advertisement, are they censoring or boycotting?
UPDATE: I found out that the ads were purchased by Cineplex Odeon. After purchasing, they decided not to run it. I assume the money will be returned, but that has yet to be confirmed.
