As a practical matter, this is less concerning to me than data breaches like the Equifax one where my social security number and everything else were compromised. I can think of ways 23 And Me data can be misused but, aside from police (who could get the data anyway), most of them are kind of theoretical or contingent on technological developments.

Like, 23 And Me data going to the highest bidder is obviously disturbing but I’m not sure it’s an immediate danger in the same way as all our SSN’s being sold on the dark web. I’d rather nationalize credit reporting agencies than the unprofitable ancestry report company.
