A: By acting in contempt of the law.

Only partially. As long as the third-party doctrine is valid in the US, they can claim that they're just integrating data from private companies with existing government records.

And those third party companies can, if they choose, tell Palantir to pound sand if they don't have warrants.

The real problem is those third parties know a LOT about us, and it's essentially impossible to opt out of their data gathering. License plate scanners and credit bureaus, anyone?

And then those third party companies, if they're interesting enough to Palantic or those using Palantir, might get cancelled state contracts, or surprise tax audits, and other pressures... totally unrelated "of course"
