23andMe admits hackers stole raw genotype data - and that cyberattack went undetected for months | Firm says it didn't realize customers were being hacked

It's data, that's all that's needed. That you or I can't think of a reason or use case (well, outside of authoritarian nation state business that is) that makes it valuable just means we aren't likely ghoulish enough.

But you can't change your genetic data, so it's a bundle of "anonymous" data that will forever remain just waiting for the right link to irreparably link it to someone.

Cheap data point now, but who knows how useful or valuable it could be if the cyberpunk Dystopia of Tech Bro Billionaire's wet dreams come to pass?

China... because China is a black hole of information and will steal anything and everything for hegemonic advantage. If that DNA belongs to family or friends of powerful people, that could lead to a future blackmail advantage

Russia, because fuck the West.
