The palantirs were made by the elf lord prince Fëanor of Valinor, one of the good guys. The one we see in the film was given to the kings of Gondor and then pilfered by Saruman. (elvish palan 'far', tir 'watch over')
> prince Fëanor
> one of the good guys
Uhhhh...
Feanor drew his sword on his half-brother and threatened to kill him because he was paranoid Fingolfin was trying to usurp his power. He compelled all of his sons to swear an oath to slay any man, elf or being in possession of the silmarils (which led to subsequent needless bloodshed).
Then he ordered and carried out the mass-murder of relatively unarmed Teleri in order to rob them of their ships.
Such actions does not a good guy make.
palantíri * (sorry, couldn't resist)
that it takes following the... (charitably) uncommon view that Fëanor was a "good guy" in spite of being a psychopathic thieving mass murderer to excuse the actions of Palantir (the company) should be an indicator that they're Bad, Actually.
This almost makes it funnier? As if it’s the folly of creators to believe that their creations are by virtue untethered to morals and ethics, and it’s only through their use by amoral or unethical actors that they become so.
