Because you have motivated reasoning to dislike these companies, even though Blackrock and Blackstone are bog standard financial services companies and a random naming scheme is easy to grab onto.
All the worst companies seem to all be LOTR themed.
Technically the Palantiri were a force for good in the hands of Elves and Men, and could still be used for good, like Aragorn using it to challenge Sauron and forcing Sauron’s hand. So that’s a defense to the self-awareness argument. In fact that ambiguity is likely intentional.
Btw I always wondered why I was seeing droves of Palantir swag on Stanford campus back in early 2010s. I wouldn’t wear something that has a 50%+ chance of being interpreted as evil.
The Palantir themselves aren’t evil, they were made by the elves long before the events of LOTR. Essentially they are just a tool.
However I heard that Thiels favourite book is the rewrite of LOTR from the perspective of Sauron, where Gandalf and the elves seek to destroy humanity and technology (at least that’s how I understood the gist, haven’t read it)
Always that Black prefix, like something out of a bad action movie.
