The Purge Palantir movement was started by activists who found out that Palantir was using their surveillance software to track migrant workers. They have done the research and show that Palantir has huge government contracts with several US federal agencies and branches of the military. The organizers talk about this movement in the podcast.

Purge Palantir has a website where you can sign up to take action to get Palantir out of our government. Actions: #1) ask your Congress person/Senator to pledge not to take donations from Palantir.
