As someone who works in media (not on editorial side but on digital), I can assure you thats you are wrong.
Most media orgs have a log of rigor and fact-checking that goes into their stories. The editorial side is typically (not always in some places) shielded from the business pressures (for better and for worse).
Its someone else's problem to worry about clicks etc.
Greenwald stopped being a credible journalist awhile ago. Just look at what he was pushing these last few weeks.
I have a lot of respect for his early work but he went on a weird tangent.
