23andMe is very open about selling people's data! More people are OK with this than you would think. And without those data sales to third parties, 23andMe would look very different. I hear (rumors only) that their customer acquisition cost is a large percentage of the kit cost, and what's left over could in no way cover running the SNP chip.
The 23andMe SNP chip is not very medically useful, and I can't imagine a doctor recommending anyone use 23andMe unless it's to find relatives to relieve stress about the matter. Doctors will order specialized tests from clinically vetted firms that have medical directors signing reports that put their medical licenses on the line.
All that said, giving people access to their own data is somewhat valuable; and when the company was started no one knew how valuable it would be. Turns out it's mostly only useful for genealogy, at the moment, and unlikely to be useful for much more to individuals.
What people really want to know can not be answered by these tests, for example, what foods a person should eat, how long they will live, what they need to do in order to finally find bliss, etc... There are a several tiny, shady, providers of this information that is in high demand by some consumers, but short supply from the science.
