You’re also missing something very important. A lot of the things these people see as “their problems” have been implanted into their heads by shitheads on talk radio, TV, social media, YouTube, etc for the benefit of the wealthy. If you’re too busy worrying about trans people and illegal immigrants, you’re not going to pay much attention to the rich fucks paying you a pittance and hoovering up the planet’s resources for themselves.
You’re making a distinction without a difference. Nobody has any fucking clue who their “genetic match” will be nor does anyone have any fucking clue who else is using 23andMe. Sharing that information with other 23andMe users is not meaningfully different than just sharing it with the world at large.
