They refuse to engage with him. "Our intention in sending the memo was for you to revise the story for publication. However, it's clear from your response this morning that you are unwilling to engage in a productive editorial process on this article" That kind of full stop to the conversation is exactly what gets people to understand they don't have a say and don't have someone who will even listen. I'd say quitting over this kind of journalistic integrity is extremely noble. How could they even request he not post his article elsewhere when he is allowed to do so. We're talking about the guy who released Edward Snowden leaks basically building the Intercept in the process and now with the overwhelming evidence that the 'laptop' stuff is true as he detailed, they all of a sudden are opposed to information leaks and claiming it's "Russia" when the photos and videos from the laptop are obviously proof that the laptop was in fact Hunter Biden's. If i was dismissed so easily about something that is integral to my profession I'd be pissed too.
