That's a royalty free copyright licence.  I believe it exists precisely
because material cannot be forced into the public domain.  The W3C have
something similar for their original web server.  I think the latter
has the normal disclaimer of liability.  It's generally considered to be
unsafe to distribute anything for which you might be held liable without
such a disclaimer.

From a consumer point of view, it is generally unsafe to use anything
that doesn't have a specific copyright licence from someone who appears
to have valid ownership of the intellectual property rights.
