A group of Gandalfs protest outside the home of Peter Thiel in Argentina

A group of protesters dressed as Gandalf gathered outside Peter Thiel's Buenos Aires home to criticize his company Palantir, which develops AI-assisted surveillance software for the U.S. government. The protesters, who sang adapted Argentine football chants mocking Thiel, chose the Gandalf costume as ironic commentary, since Thiel has dismissed the character as a "crazy person" while naming his company after fictional objects from Tolkien's work that are known for their corrupting influence. The protest reflects broader concerns about Thiel's involvement in surveillance technology development.
