It’s likely no shock that the popular biography of Elon Musk is more entrepreneurial myth-making than unbiased fact. Now Musk’s long estranged and recently outspoken daughter, Vivian Jenna Wilson, is alleging that her portrayal in the book was “genuinely defamatory.”

On Monday, Wilson addressed author Walter Isaacson on Threads, Meta’s competitor app to Musk’s Twitter/X. Isaacson has authored the 2023 best-selling biography Elon Musk in addition to other ‘great man’ public figures like Albert Einstein and Steve Jobs.

In a series of posts, Wilson argues that while the book treats Musk like a tortured luminary, Isaacson “threw [her] to the wolves.”

“Elon was your darling Tony Stark apartheid-american hero with a semi-tragic backstory who was saving the world and you were too f*cking cowardly to write anything other than a sad excuse for a puff-piece,” Wilson wrote. “To further this goal, you portrayed me in a light that is genuinely defamatory and I’m not going to mince my words.

“I was treated as a VILLAIN BACKSTORY-ORIGIN to excuse or explain away his behavior. As if my whole existence was nothing but an inconvenience to HIM.”

Wilson added that she was deadnamed and misgendered throughout the book. Even in moments when Isaacson attempted to get her name right, he evidently failed.

“I go by Vivian by the way, not Jenna as the book implies,” she wrote. “Jenna is what my friends from high school and my mom calls me. If you genuinely knew what you were talking about that’s how you would’ve referred to me.”

How could such an esteemed biographer fail to get a detail like that correct? Apparently, he never contacted Wilson, despite spending two years in Musk’s company to research the book.

“I know that you claim that you ‘reached out to me through family members’ but I found out about this thing’s existence literally a MONTH before it was released,” Wilson said. “So either you are completely f*cking incompetent at the most basic aspects of your ‘job’, or you are weaponizing your own lack of effort to try to lift the blame off of yourself because you knew damn well what you were doing.”

What, Wilson alleged, he was doing was trying to “catch headlines as part of this culture war bullsh*t” by portraying her in a negative light.

“You knew that I was gonna be used as an example of ‘how the children are being brainwashed by the trans agenda’ because you did it yourself and then proceeded to blast it to every news organization to use as an ad to sell more copies,” Wilson wrote.

“The fact that this book may have been used as justification by parents to not let their trans child obtain potentially life-saving medical treatment f*cking HAUNTS me. It always will.”
