not sure why this is downvoted, it's a fair question. Conspiracy theories are fun but I think the apparent trend reflects two complementary forces: 1. More media attention to genetic testing in general (because of 23andme, other companies entering the market) 2. A great deal of concern from the medical genetics community that these tests, or at least some of them, are way ahead of the science. Geneticists who are drawn to the field out of a desire to impact health take exception to seeing their work used to take advantage of vulnerable groups. (This can go to the extreme: some geneticists would prefer that the science remain 'pure' and will probably never think it's ready for prime time.) Disclosure: lapsed geneticist
