This is great. I had a 23andMe test done years ago and one of the reasons why I chose to do it was because my genetic data might be helpful for others. I personally don't feel like I 'own' my genetic code and I'm quite happy to let scientists analyze it. However I understand while many people do not feel the same way.
I'm relatively paranoid when it comes to privacy and also did 23andMe for similar reasons. I stopped thinking of my DNA as a secret when I realized how impossible it is to keep other people from having access to it. Once someone knows it, you cannot change it like a password. DNA is an anti-secret. You share it everywhere you go and cannot stop. It's no more secret or personal than your shoe size or height.
The idea isn't 100% security or nothing, but to make it harder for the data to be exploited.
Lots of our personal data isn't a well kept secret, but I also don't give it to any company that asks for it, unlike my shoe size.
