I still can't believe someone named a company Palantir. In Lord of the Rings, the palantíri fell into the wrong hands and were used to do literal, honest-to-god evil. It's like naming a company Death Star.
The Palantir were "good" objects in The Lord of the Rings. (As opposed to the Ring, which was inherently evil) The Palantir were used for thousands of years to protect the kingdom. Even during the time of the books, when being used by the most powerful evil bad guy, the right good guy could take back control of the Palantir "network".
