23andMe can do whatever they want with your data. It totally boggles my mind that someone would give a private company legal, full, and complete access to what makes you, you. We're still in the infancy of understanding what we can do with our genomes. Giving all our information over to an entity without a fiduciary responsibility to protecting your personal data is just idiotic.
My genome is public on Harvard's Personal Genome's Project [+]; why would I care what 23andme does with my data?
