I was talking about the companies Palantir and Anduril. Whoever chose those names are not true Lord of the Rings fans because even though they used names from Lord of the Rings they should know that Tolkien would never have approved of it. Thus, they are not Lord of the Rings fans but rather are just using the names for clickbait purposes. To me personally a tech bro indicates a more casual, nonprofessional - someone who is interested in tech as a hobby. They might do bit coin mining or some casual stock investment but they are not big corporate overlords like those who run Palantir and Anduril. Though of course I could be generalizing too.
