Edit: To answer some comments; it's misleading because Apple is rejecting some applications which use Dropbox. Or, rather, a single one that we know of. For a reason other than "Dropbox is used by the application", to boot. A better title would explain what was actually happening (no offense to OP; I'm glad s/he cut out the editorializing). But I'm sitting here at -4, so it's unlikely this is seen :)
