Thus comment and the parent are spot-on. The main protection against the adversarial use of genetic databin the US, GINA, is currently facing several challenges, mostly through the backdoor of opt-in employee wellness plans.

Additionally, while the SNP- format generic data provided by 23andMe is of marginal medical use to the average consumer, it is very valuable to insurance companies and others constructing population-level actuarial models, where a very tiny increased probability of developing a condition is enough to justify increased rates.

And finally, as these relative-discovery stories suggest, there really is no such thing as anonymized genetic data above a panel of a few SNPs. This data is part of the inherence class of factors in multifactor authentication, and can even be derived from pooled anonymized data by a motivated party.
