Seems like what he did was take Umass' Labeled Faces in the Wild (LFW) dataset, combine all the faces together and generate a composite rendering. Hardly a representation of "What your face looks like to Facebook".
Articles like this do little to advance the discussion of the real concerns around facial recognition other than scare folks into an Orwellian vision of the future a la Hollywood and Minority Report.
In addition to the work that the NTIA is doing around setting privacy standards for facial recognition applications (http://www.ntia.doc.gov/other-publication/2014/privacy-multi...) there are a lot of companies using the technology for good, but it is very difficult to get as much press and attention for those types of positive stories.
For example, my own company, (http://www.kairos.com) is working with some very brave and passionate guys at HelpingFaceless.com in India who are using facial recognition to help combat the growing problem of child trafficking and enslavement in India.
