It is more likely they just don't care about the oil industry and focus their attention elsewhere. I would wager that most people assume that large corporations have dirty secrets. e.g. I listen to a guy that goes exposes the conmen in the UFO community. The reason the guy focuses on UFOs is because he believes that when he was younger he saw a UFO. Over time he slowly realised over time that he had been lied to by these conmen. He isn't interested in the truth about the oil industry, he cares about the truth around UFO encounters because that is what he cares about.
