I’m not sure if this deserves the downvotes or not. I get the point that right leaning and left leaning people look at these sources differently. I imagine there are differences with respect to their publishing standards and that is perhaps what is attracting the downvotes.
I get the point though, the partisan divide makes it such that any programmatic banning of a source comes across looking partisan. I think this is why Twitter and others took so long to ban some publishers.
