Eugenics can sound pretty appealing until you take a moment to really think about it and aren’t the type to just be okay with whatever suffering you may cause in the name of the “greater good”.
And making it illegal to have children with close relatives is a form of eugenics, i.e. it’s still practiced and widely accepted in most western countries.
I’d assume that most governments (other than the US) don’t have easy access even if E2EE in WhatsApp etc. is a sham - these companies are definitely intent on keeping the pretense up, and smaller countries aren’t able to disprove it.
