"TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION" pretty clearly applies to the package accompanied by the license. I looked at the Wikipedia page and this wasn't raised as one of the objections. Do you have a link to some lawyer complaining about that? If the OSI lawyers said it's equivalent to a public domain dedication, that seems useful in countries that don't have a public domain.
