I see a lot of people making claims about 23andme that haven't used the product, and I just wanted to inform people that in the contract you sign with them, they only share your data if you opt-in to it. They make this all very clear. You can also have them discard your sample and delete your info if you haven't opt-ed in to the research program.
Now trusting that 23andme is actually abiding by these rules is a different conversation.
