You convinced me that, as I was already suspecting, there is no more risk in having your dna public than, for instance, having a picture of you on the internet. Arguably, even less.
"no more risk" is an odd way to frame it. Its all compounded. Having a pic of yourself online is a risk. Having your DNA leaked a risk. Carrying a cell phone is a risk. Using Google is a risk. The more risks you take you more likely you are to get screwed over.
