The policies for the data and the retained sample are described by the 'babysfirsttest' site above as allowing use "for medical intervention, counseling or specific research projects which the California Board of Health approves" and "anonymous research studies". Those sound about equivalent to the 23andMe policy... and at a similar risk of reinterpretation or rule-bending if organizational priorities or technology change.
