Earlier quoted context omitted.
Did you see them make that demand? Their wording that he published implied that it would be detrimental to The Intercept, which would be a fair claim. I think you can suggest it was careful pressure or negotiation, but it didn't read as a demand to me.
Language like that is setting up the basis for a lawsuit. It’s absolutely a demand not to publish it elsewhere. In fact it’s a thinly veiled threat if he does. You have to read this knowing there is an existing contractural agreement that Glenn is expressly allowed to publish elsewhere if they do not publish. So the only basis to stop him from doing that would be to allege it would be “damaging” if he did.
My read of the comment was as a negotiating point - they want to encourage a result but not make a legal demand. i.e., he can just ignore it if he doesn't have any consideration for The Intercept brand that they share.
