From my understanding of the article, the research they're referring to has to do with biomarkers (which aren't always genetic) and brain scans. If you go to the ADNI site (link: http://www.adni-info.org/Scientists/LinksForDataCollection.a...) you'll see that it is indeed possible to download some anonymized data and scans with less stringent approval. So, maybe basement hacks are indeed possible.
