The Palantir are not evil creations in the book iirc. They were used by the great kings to see whatever they wished.
Heck, even in the book Aragorn uses the Palantir to make a critical decision turning the tide of battle.
A better metaphor (accidental or not) for surveillance technology I've never seen.
That’s not true. They were only dangerous to use as long as an insanely powerful immortal demon god had one. If you used a Palantir he would notice and draw your eye toward him. He could then make you see what he wanted you to see, unless you were strong enough to resist. He corrupted Saruman and Denethor merely by talking to them, showing them misleading things, and convincing them that he could not be defeated by any means. Kill Sauron and the Palantiri are safe to use again.
The tools are neutral. It is the users who are good or evil.
It’s the same with the Throne of Amon Hen, fwiw. It’s only dangerous to use because Sauron will notice that you’re using it.
Alt: Be Aragorn and wrest control of the Orthanc stone from Sauron.

Denethor (?) tried to use a Palantir for good, but went mad after viewing its selections for years.
(you might argue it reflects certain social media outcomes ofc)
