Not quite. As legal explained to me -- it's too legally ambiguous for some entities to feel comfortable using because your only fall back on public domain is copyright, which can be overly restrictive, and the usage rights are undefined and enforcement or rights can be applied or modified at will by the copyright holder in the absence of a clear license. And that copyright, even in the public domain, often exists inherently. That's not an issue for me at my $corporation because they are sane, but apparently that's the argument.
