Do you really want big tech and alphabet soup agencies to have the social media history (secrets, likes/dislikes, usage profile) of our future leaders?
Not exactly compelled to add the Chinese government into the mix on top of that. The state of privacy being internally dire already doesn't mean I'm obliged to be compromised and debased on an equal-opportunity, global basis.
They already do, so I don't understand the point of asking this. Why does another government (that is becoming increasingly at odds with our own by the day) also need to have this data?
