Earlier quoted context omitted.
I suppose. But once there's a bunch of stuff online that's linked to your DNA data, anyone who has your DNA data can correlate it all. And tie it to your true name. Bottom line, I see no compelling upside to putting ones DNA data on the Internet.
That's why I would like to send my DNA in anonymously; I don't want to link anything to my DNA data.
23andme knows my DNA. They know my email, and possibly where I bought the kit.
They don't know who I am, I hope.
And, regardless, I suspect the de-anonymization will be either so haphazard or so thorough in the future that it's not a primary concern.
