But in all seriousness, you should know it is actually possible to use data towards good aims. Policy makers can use data to produce better answers to questions exploring issues like poverty, disease, crime, financial literacy, etc. Setting up a massive survey is slow and extremely expensive, and that makes it extremely hard to iterate on findings. Getting answers years quicker makes it possible for the government to develop better policies, and that's a good thing. Sure the Nazis were evil, and information enabled the Nazis to be more efficient and effective at implementing evil policies. But an un/less-informed government isn't a goal to strive for. Good government implementing good policies is a goal worth striving for, as there are some problems that can only be addressed at government scale.
Considering I know what kind of data is available, I sincerely doubt this is what is happening. Does that mean, that it's all super evil bad bad stuff, nah, but it is exploitable for evil for sure.
