I don't disagree with you that Vanity Fair is probably a bit anti-Thiel or anti-right in general, but I don't know what "generated" is supposed to mean in this context. I don't see a lot of mockery or ridicule in this particular article.
I also don't know what the "hit piece" part is supposed to be. He is a Trump delegate, he did finance Gawker's bankruptcy, he does espouse the ideals presented in the article, and he has invested in life-extension technologies. Can it be a hit piece if it's actually correct?
