A Wikileaks that just makes available the documents they have without the need to try all tell people what they should think about those documents might have some value. Of course, it might also be impossible since somebody has to make the decision whether or not to release a document (for example, if they believe release might endanger lives) and that can be seen as a form of editorial control.
And what would make people stumble upon and wade through the thousands of documents? Not everyone has the time or interest to read everything that comes across their path. While I hate editorializing, it is necessary to get most people interested enough to read about it.
