You can be traced in many, many ways. From all the websites you visit, the accounts you have, social media posts and pictures, connections with others, camera's outside, your car, your job, whatever more. There's very little true privacy in modern urban life.

Yet, while privacy issues are a point of concern among geneticists when it comes to direct-to-consumer genetic testing, the general points of caution are directed to relational and emotional issues. Many people think little of the relational consequences genetic testing can bear, where family members are implicated often unwillingly. Another point is that people often make up wrong conclusions about their results and see them as some infallible passport of who they are, while the tests are limited in what they actually can tell. Or let's say tests show you have a disposition for increased disease risk. I doubt many give it a really good thought of whether they truly want to know and live with said knowledge for the rest of their lives.
