I’m honestly not interested in 23andMe so I never bothered to fact-check so take this with a massive grain of salt but I did watch Linus (from TechTips, not Linux) rant about the privacy problems it has. I don’t trust him about these things but I’ve also watched him rant in favor of letting the spyware consumer features of Windows stay on because they’re so great and it’s not that big of a deal, so 23andMe has to be doing something very, very wrong.
