NHS England is rolling out software from Palantir, a US company, to manage health records, which has raised concerns due to Palantir's history of supporting mass deportation and surveillance. The company's founder, Peter Thiel, has also expressed negative views about the NHS. A campaign is urging people to email their local NHS trust to demand they reject Palantir's software. The goal is to prevent Palantir from taking control of the UK's healthcare system.
