It doesn’t have to be to someone’s detriment - it can just be unethical. The obvious agenda here is for a private company to use DNA data sets to develop/streamline drugs and profit handsomely (or write off any losses on their taxes). To me it is offensive that as a society we tolerate shit like this, but maybe I’m an outlier. Though, like most other commenters, I don’t see how anyone who signed up for this service did not see this coming.
