A touch smarter observation would be to note that every use of a Palantir in the story is deceptive or manipulative, at least to one party.
Aragorn deceives Sauron into believing he had the one ring, when he didn't... https://twitter.com/icpetrie/status/1320156668165001216

Pippin is observed by Sauron, which misleads him as to the true location of the ring.

Denethor is shown the great strength of Mordor, which was true, but also incomplete information: it made him despair of any hope when clearly there was still hope given that Gondor survives.

And in perhaps the most complicated set, Sauron manipulates Saruman, corrupting and dominating him through the Palantir, while Saruman at the same time deceives Sauron, pretending to be his faithful servant while still scheming against him.

In short, every time they are used, the Palantir show true things, but do so selectively such that they deceive at least one party using the stones.

Which...nevermind. This is a brilliant analogy for a Big Data firm. Palantir: True Information That Always Deceives.

Perfect.
