So "differential privacy" pretty much sounds like someone gets to modify the results of a census and how it gets modified is entirely up to their discretion.
Seems like something that could be abused to achieve political objectives.

know how you can buy "anonymized" data from data brokers and drill down until it's not anonymous anymore and in many cases point to the exact person? differential privacy would prevent that kind of thing.
If someone actually wanted to achieve political objectives by tampering with census data, there are better means than tampering with homogeneous statistical fuzzing.
I hope so. What are they?
I guess someone could fiddle with the noise, but then why not nudge the originals? Or more insidiously, control what is published?
Anyway you either ensure any analysis is reproducible or not, if adding noise is one of the steps just make sure to fix the seed.
