Holy hell, you need to go watch the big tobacco trials of the past to see the CEOs knew exactly what they were doing. And then how much they spent on outright buying scientists to say bullshit so they could drag the matter on for years.

Tobacco set the stage for companies to use doubt of every kind to hide their intentional actions.
