"The SNP chip method that 23andMe uses was never very good at providing useful genetic information. Its advantage has been its low cost. But as sequencing gets cheaper and cheaper, SNP chips have already largely become obsolete for most genetic testing."[1] Basically, 23andMe has always oversold the results available from the crude SNP chip technology they were using as a hook to have people PAY to send them DNA samples that would make them "members" of 23andMe. Then the members are reminded to send in personal health history information to be put into the 23andMe database so that 23andMe can data-mine that and try to figure out what the DNA actually means[2]--which no medical geneticist knows to any precision at the moment. That business model of suckering in paying clients today for the promise of an unknown amount of actionable information in the future is why 23andMe was trying to stonewall the FDA while marketing what was plainly a direct-to-consumer medical device. It's not surprising (see first link here) that the FDA is not going to let 23andMe get away with that.
