also, I don't trust them with my DNA data anymore.
Notably, "Percentage of Requests Where Some Data Produced" is all 0%.
SNP sequencing is the ultimate fingerprint, far more individually identifying than anything else as of yet. Imagine having 900,000+ criterion to cross reference to determine identity.
Now, obviously, you're asking them to sequence your genome, so they're getting personally identifiable information. If you have relatives who have done their 23 and me work-up, then they'll be able to tell that "John Doe" is related to Gunther Kumar, or whatever. In my friend's case, that's not likely to be an issue as they have few living relatives, most of whom are very old and would have no interest in 23 and me. YMMV.
