If the health insurance industry is several times larger than car insurance then there must be a very high financial motive for Ancestry/23&me to sell your curious aunt's DNA data which is also linked to relations.
At least the health insurance industry is legally prohibited from charging different rates to people based on DNA. So, at most, they can use it to try to get you specialized care.
No shit. Plus 23 and me is in deep financial trouble last I heard. Someone out there is drooling over that data set.
I know otherwise smart people (in the analytical sense) who paid money to hand over their most sensitive biometrics to these companies. And they’re still like “the data brokers can have it, what are they gonna do?”
