Really, it's that publishing at the scale of a big paper requires separation of responsibilities. The workflow hasn't caught up to the new medium -- and neither has the publishing software. Newspapers are notoriously slow to adopt new tools. The New York Times was composed using linotype machines until 1978 -- about 20 years late -- and when I worked there in the late 1990s the pagination system (essentially, the CMS) was a green screen application running on a few rows of PDP-11s.
