> Why not? Some of the best investigative journalism I've read has been on Substack. Do you have examples of important stories broken on Substack? Greenwald has broken a few huge stories in his life, but in general he's not an investigative journalist. Rather, he's a political commentator, and that's what he does on Substack. In fact neither Greenwald nor Laura Poitras was an investigative journalist; that's not why Edward Snowden selected them.
