I think it’s kind of funny that they mention to allow the flat earth comments when just previously saying that they want to prevent cult-like behavior; flat-eathers won’t listen despite the evidence. Then again, verifiability doesn’t seem to be holding strong these days
I think the point of big data is to collect enough information to extrapolate other qualities about whatever you want to know, so if everyone is on the list then you have no patterns to go off of besides “on Earth” or “in X country”.
Side comment: if 99% of people were on the list, the the govt could just oppress everyone with a 99% accuracy rate. It’s entirely possibly they could pick a proportion drastically lower than 99%
