Is it ethical To Act Without Saying

When a commercial is made, a director pays actors to lay in it. When a commercial for an opinion on how the public feels about a political view, the director pays an actor, and says that there were actors paid. It isn’t ethical to not say that there were actors paid. For example if there is a riot because a store doesn’t pay enough to its workers. But someone makes a statement and says that the store is too expensive to shop at. That person makes a commercial and pays 50 people to walk outside of a building and yell that the store is too expensive. People would believe that.  People these days look for someone to say something and then they follow that person; even if it isn’t true. Not saying that the actor was paid is not ethical because it makes rumors that aren’t true.
