This reads as though you're implying The Intercept existed independently of Greenwald. They didn't, he co-founded The Intercept. He ought to (and I imagine, he does) have seniority on any editor.
I think it speaks volumes about him as a journalist and his journalistic integrity that he setup The Intercept as an outlet where he and his co-founders don't rule with iron fists. His submissions aren't treated specially. It's not his mouthpiece.
