Someone pretty familiar with Greenwald posted a pretty thorough, point-by-point takedown of the piece he wanted The Intercept to publish, and ended up publishing himself: https://twitter.com/emptywheel/status/1321923054499495938?s=... Frankly, if you read his original piece, it's exhaustingly shoddy. To say he needs an editor is putting it lightly.
The irony of HN upvoting comments that do the same op-ed ranting on their own issues and haven't seem to have thought critically about the article in question or the emails Greenwald himself leaked (which paints the publishing story quite differently from his version of it) is wild but not unexpected.
