I'm not speaking specifically of Greenwald here. Just pointing out that independence is no guarantee of trustworthiness, either. People love news that affirms them, regardless of the truth, and sometimes rigid, prominent rejection of the truth can be very good for the brand.
You can still get something a lot like the old, boring news from wire services. When I need it, that's where I go. But it's boring, so I don't keep up with it. Real news at that scale would be expected to be boring.
I should pay more attention to the local news, which has long had the same problem -- the motto was "if it bleeds, it leads". Local violent crime is at least a little relevant. But the important stuff is often even more boring: plans for a new park, a forthcoming road closure, a report from the school principal. Relevant and dull, just what I want.
There's still plenty of room for tribal garbage, but at least it's easier to put into perspective.
[1] I feel weird writing that in a rare period where the news actually contains actionable information -- though that's partly because it happened at a time when the government should have been giving me the information and I should have been able to trust it. But I'm setting aside pandemic as a rare case, hopefully to not be repeated soon.
