Potato potato. Palantir explicitly provides tools for data analysis and operations for government and enforcement agencies. Postgres is a database used for virtually anything that needs a database. The two aren't the same.
For the record - Palantir isn't 100% culpable of a government resource abusing its capabilities, but it sure unlocked a whole bunch of capabilities that were either too expensive or too difficult to do previously (for example, storing records in an RDMS).
> Palantir, the tools came with a robust ACL solution.
ACLs require humans to configure them. Uber also has a robust ACL. It doesn't stop someone in the org from using and abusing its God-mode.
