Interesting that in the page you cite, they state specifically the
opposite of what you're saying:

<begin gnu>
Public domain software
======================

Public domain software is software that is not copyrighted. It is a
special case of non-copylefted free software, which means that some
copies or modified versions may not be free at all.

Sometimes people use the term ``public domain'' in a loose
fashion to mean ``free'' or ``available gratis.'' However,
``public domain'' is a legal term and means, precisely, ``not
copyrighted''. For clarity, we recommend using ``public
domain'' for that meaning only, and using other terms to convey
the other meanings.
<end gnu>

I overlooked the specific legal meaning of "Public Domain" and therefore
was incorrect in the assertion that the releaser of such software "only
has their implicit copyright". 

However, I was still correct in saying that just because you release in 
the public domain doesn't mean you're releasing "free" or even more 
generally "open source" software, which was mainly the point I was
trying to convey.
