Palantir is a private company whose product's development was incubated and developed at taxpayer expense following 9/11 (they essentially researched all of their technologies on the taxpayer dime on govt contracts, then took those technologies and created their product). It's an asshole company that doesn't give a shit about the constitution or human rights.
They also use Congressman Hunter as a paid shill to push their product all over the government as if its a panacea to every data integration issue. Its not.
