I received a DNA test kit for Father’s Day. I’m not going to use it. Here’s why. Submitting a DNA test to Ancestry requires signing up for an account and agreeing to their terms of service. I can imagine lots of people do this without actually reading the ToS. The Ancestry ToS is a contract. When you sign it, you’ve entered into an agreement that allows them to, among other things, take an in-perpetuity license to your DNA.
