Thats a good question. I think one of the reasons was the problems with vandalism, and published vs non-published articles. However this was before I came to wikinews so I probally shouldn't be answering this question. (Vaugly remember something at the water cooler when I first came.)

>> Why isn't wikinews searched when I conduct a Google News search?
Google have agreed to include Wikinews when various people have requested
it, but I gather they then took it off the search again because they were
concerned about how it might change after they'd picked it up. I think
you'll find a discussion about it in the Watercooler archives (best to
search through Google!)
