The directory is a source of information, not a prized pagerank giving oracle as some view it. I think they should follow wikipedias lead in this case. Take that with a grain of salt because I also believe that websites using google maps should nofollow the link of the map itself. Those maps show up on your site but they are "retrieved" via a normal links which passes pagerank to google, yeah, like they need it. To paraphrase Matt Cutts, if your site isn't about maps, nofollow that Google map because its off topic!
nofollow belongs in many places, dmoz included imho.
