Thought it was an interesting argument even though I strongly disagree with it.

The fact is that if you’re worried about privacy, you should be far, far more concerned about all the data that various companies are hoovering up about you based on your online activity. Are you browsing the web only in private or “in cognito” mode? If not, then companies are already buying and selling tons of information about you–information that is far more revealing than a SNP chip. Do you have a Facebook, Instagram, or TikTok account? Then you can be sure that Facebook and other companies know a great deal about you

I use private browsing, VPN, avoid corporate social media, etc, but even if I didn't this isn't a good argument. Some sort of incel-like logic of "You fucked all those other guys, why won't you fuck me??"

But wait, some argue: genetic information might be used to deny health care coverage! [..] But even in the U.S., this fear is not a serious concern, because your SNP data reveals almost nothing useful about your health or your future risk of disease.

Apart from saying "This wouldn't be so bad if the world was a better place", insurance companies would love the information that 23andMe put behind the warning flag. Their own site says:

Knowing about genetic risks could also affect your ability to get some kinds of insurance.
