Is there any evidence that they actually stopped him from running it elsewhere, or that they actually refused to publish it? The start of the editor's memo specifically states that they are "comfortable with publishing". And he did publish it elsewhere (on Substack). So both claims are weak. It seems like he was looking for an excuse to bail from The Intercept, and this was it.
