You just don't live in the real world. Oil companies, like my old industry (nuclear power) know very well that it is not a symmetric competition. Not least because the first response to anything you put out is "I don't believe you because you work for them".
Scientists in these industries are rewarded for doing stuff that helps the bottom line.
Academics and those working for Greenpeace, etc, are judged by column inches or, these days, "likes" and re-tweets. They have an actual incentive to dramatise, and this introduces bias.
