Also, tobacco companies and oil companies famously got into trouble from revelations that they were perfectly aware of their negative impacts. For the gambling and alcohol industry, it probably wouldn't even make the news if some internal report leaked that they were "aware" of their negative impact (as if anyone thought they would not be?)

Social media is way down on the list of companies aware of their negative impact. The negative impact arguably isn't even central to their business model, which it certainly is for the other industries mentioned.
