First, let me point out how interesting it is that I was clearly responding to your title, but instead you are trying to defend the words that Reich used in the tweet.
But anyway, your title says "no corporate news story." That literally means no mention whatsoever, but I would fairly interpret that as meaning that it's buried or there little to no mention of it. Which is untrue, I mainly consume "corporate media" for, as biased as they are, they are still hundreds of times less biased and more reliable than other news "sources" I've come across. And these are all things I've know about from my typical news consumption (with the exception of OT expansion, this is the first I've heard of that). So I disagree with your "no corporate news" claim. I think it's actually patently false.
What Reich here means is that they aren't the main news stories of the day. None of these single things is ever going to be, on it's own, the biggest news of the day. But it's the constant little steps that are good. And it's not like these are being hidden, it's just that none of them are going to be as popular as the main news stories of the day so they aren't getting the same traction.
