The paternalistic lecturing around here is unreal. Grandparent didn't ask for your opinion about 23andme privacy policies, and it's not remotely on topic.
To be fair, you aren’t making the decision just for yourself when you sell your data to 23andme. You’re doing it for all your relatives and descendants too. The GP made the pint flippantly but I think it is worth seriously considering whether business models like that should be allowed.
Nitpicking individuals is not likely to address that problem. And it wasn't even close to the subject of conversation. This is simple common decency. It also happens to be HN guidelines:
Eschew flamebait. Avoid unrelated controversies and generic tangents
