I'm not sure how popular GDN is, or how well promoted the news item is... but you would expect more competition than that. I wouldn't say no to any free WiiWare title ;)
As for everyone having the game... having the sales figures here, I doubt it - although its possible a lot of the WiiWare fans that use those sites may have it.
