Seriously. What’s the threat model here? A human clone? Someone hacking a police database to replacing some criminal’s dna record with your record? None of these are plausible.
Even the reporting about compiling a list of people of Jewish ancestry is fear mongering. An antisemitic troll post? Absolutely. An actual novel threat? Well, probably not much more than a regexp and phonebook.
Seriously. Give me a real scenario that has been demonstrated that uses this information in a way that someone with… oh $10 million in resources could do. I’ll wait.
