Willow Garage isn't the original source. They made the platform, but the developers of the "common sense" system, the owners of this robot, and the people who actually made the video, are from the University of Tokyo JSK Lab and Technische Universität München. If you read the link you posted, you would see that Willow Garage properly credits them as the original source.
Edit: Also, the fourth word in TFA is a link to Willow Garage. Your entire post is wrong.
Willow Garage does, in fact, have a blog. And they did, in fact, post about this four days ago: http://www.willowgarage.com/blog/2011/10/04/jsk-and-tum-teac...
Did singularityhub mention the original source? No, of course not.
