I’m honestly asking what the impact to the users is from this breach.

The stolen info was used to databases of people with jewish ancestry that were sold on the dark web. I think there was a list of similar DB of people with chinese ancestry. 23andme's poor security practices have directly helped violent white supremecists find targets.

If you're so incompetent that you can't stop white supremecists from getting identifiable information about people from minorities, there is a compelling public interest for your company to be shut down.
