This is a pretty uncharitable read. The Intercept's issue with Greenwald's article is not that it is "not convenient," but that Greenwald doesn't adequately support his own conclusions on a story with tenuous evidence. That's not hack journalism; that's journalism. Journalists and editors are obligated to review stories and ask the question "is what we are reporting true? is it relevant? is it timely?" and if the answer to any of those is "no" or "we're not sure," to hold off. THAT'S the standard that The Intercept is using, and that's where Greenwald fell short. Anything less is the very definition of hack journalism.
The founders never imagined a situation where a very few private citizens would have the power to censor the speech of millions of others. Nothing even remotely similar to that existed at the time and there was nothing to suggest it could ever exist. The US Constitution is also a minimalist document so it wasn't concerned with enforcing behavior between private citizens.
Furthermore there are a few private outfits that have near a near monopoly on public speech, so they have the effect of censorship.
You'd think the democratic party would have learned after 2016 by nominating another clinton. The seem to feel that supressing negative stories is just easier than answering them. Nominating someone like Sanders would have at least allowed the issues to be discussed.
