But the strength of differential privacy is that you can now make this tradeoff explicit and quantify it. I always liked it because it offers a mathematical solution to a policy problem, but then of course it's up to us to decide what parameters and tradeoff to choose. Also, some data might just not get published at all if the privacy implications are too problematic, so differential privacy might buy you more signal!
Yeah, the main issue with differential privacy is that you need competent government officials making decisions who understand math beyond a high school level.
It offers a mathematical description of a policy tradeoff, and the policy makers are apparently setting one of the parameters to zero.
