Should governments ban tech surveillance companies like Palantir from public contracts?

Context

Palantir Technologies is a data analytics firm that builds surveillance and intelligence systems used by government agencies, law enforcement, and immigration authorities. The company has become controversial because its tools can track individuals and populations at scale, raising concerns about privacy, civil liberties, and whether such powerful surveillance capabilities should be outsourced to private contractors. The debate centers on whether governments should continue awarding public contracts to surveillance firms, or whether the risks to privacy and democratic oversight justify exclusion from government work.
