This isn't entirely true. Copyright isn't some magic thing that appears
out of nowhere, it's a legal construct. The fact that in the US
something is automatically copyright when you create wasn't even always
true. In fact, it wasn't true until the latter quarter of the last
century, something that probably changed in many readers of this list's
lifetimes. And that's just the US, we must remember readers of this list
can be in many countries with many differing laws.
And even then, there's a difference between whether the author has
copyright (this can't be lost or revoked) and whether copyright
restrictions apply to a work. Copyright rights can be granted to someone
else. Thus, if someone grants equal rights to an item as they hold over
it as their creator, it has no restricted copyright. I think what was
meant by "no copyright" is that there was no *exclusive* copyright as
the rights may be granted equally to everyone.

It was clearly a statement about license though, rather than
availability, so I don't think this interpretation is sound. The
original line was "This version cannot be closed again, and will remain
in the public domain forever." in response to a statement about closed
source. If it was simply about availability, the first half of the
sentence would really be irrelevant.

This is a little bit unclear. The copy that was open-sourced remains
open forever. The original copyright holder still holds the copyright
and can re-license it under something else with later closed source
modifications, allowing the GPL version to become outdated (assuming he
can stay ahead of the curve). Whereas BSD means anyone can create
closed-source derivatives, GPL simply means only the copyright holders
(as a group) can create closed source derivatives. As you yourself
stated, you can't really give up copyright under current law, just grant
others a portion of your rights.
