Even if you don't care about your genetic privacy, your parents, siblings, and children might. You are giving away approximately half of their genomes, more than enough to separate them from non-relatives. You are also giving away a quarter of the genetic information of your grandparents, aunts and uncles, and nieces and nephews; a eighth of that of your cousins, etc. In general, your genetic sequence is not truly "yours" alone but belongs to your family. Are you prepared to ask all your close relatives for their permission? If not, what gives you the right to publish their genetic information without their consent?
