So palantir analyses pretty sensitive data, for instance health data from NHS. They may not be able to share the data itself but are there any safeguards against them using the knowledge they gain from these analyses to consult health insurance companies for outrageous amounts of money so insurance companies can fuck people even more by grinding stats?

Same goes for them analysing surveillance data. Any safeguards against Palantir consulting fascist political parties on results of these analyses so they can more efficiently carry out fear mongering?
