>AFAICT, Google's use would be encompassed by "any program/web page from which you directly link to/access any information contained within the Open Directory, in whole or in part, or any derivative work thereof." That use requires attribution according to the ODP License, unless a separate agreement has been established.

That ODP description appears under a link to the Google Directory category the site is listed in. On that page the attribution can be found. I suspect either those in charge of the ODP consider this sufficient attribution, or at least such a gray area it isn't worth making an issue over.
