It's a software company, it sells software. You can literally go read the docs. It doesn't magically bypass the law anymore than Microsoft Sharepoint does.
Your link and description of it as a software company are irrelevant to the discussion, which concerns their retention and use of personal data. I welcome anyone to give their disclosure a critical reading. (They promise to follow the law- whew!)
Do you expect palantir's public documentation to explain how they operate as a spy agency?
