"Needs to escape their echo chamber and read other stuff" is a bit too strong, but if you moderated it to "would benefit from escaping their echo chamber and being exposed to other stuff" then yes, I would take that position for literature preferences as well as political news.
I sometimes read literature outside my comfort zone. Sometimes I put it down -- not for me. But occasionally I discover a new genera I enjoy.
The trouble with political content is the style rather than the content, I think.
If you see ads for Ground News on YouTube they make it sound like you need add up what the right-wing ideologues say and what the left-wing ideologues say you get the truth. I get accused of being a “centrist” when I point out that people are using a toxic, hateful and othering style of communication (e.g. capitalizing Black doesn’t do anything about the difficult and long-standing problems of racism, maybe even mocks or trivializes the problem, but it sure polarizes the world into big B and little B people)
