I think that point is that everything is covered by copyright, by default. This is true for all entities - corporations, individuals or government. It's automatic.

The works of the federal government are a well known exception. And while I'm sure there are some state/county/city governments that also place their works in the public domain that's not the default.

It's a pretty fair generalization to say that if something wasn't produced by the federal government that it is most likely covered by copyright.
