I have to say that I am not surprised to hear this. I know SBF had been denying any wrongdoing.
An article here addresses the issue in more depth: https://www.yahoo.com/finance/news/sbf-trial-witness-glitch-ftx-155954148.html
What I find interesting is that if the evidence is so overwhelming against SBF, which it appears to be, why would SBF not take a deal?
Well, narcissism is a personality disorder listed in the Diagnostic and Statistical Manual V -TR https://dsm.psychiatryonline.org/doi/book/10.1176/appi.books.9780890425787
The simple answer to why a narcissist would lie is that it is done so to inflate their ego, even when evidence is presented that refutes their lie.
Now, I have never met SBF (and don't want to). I am not formally diagnosing him. I am a psychologist and have met many narcissists through my work in the mental health field. I am just thinking and writing about the traits displayed in by SBF. I find this case to be fascinating on a professional level. I also find it important for the future of cryptocurrency. As I have written about in the past I believe having legitimacy to cryptocurrency and holding fraudsters accountable will only serve to improve cryptocurrency in the general publics eye.
I have also read about SBF and his lists of pros and cons of dating him to Caroline Ellison. https://www.businessinsider.com/sam-bankman-fried-pros-cons-list-dating-caroline-ellison-2023-10#:~:text=Sam%20Bankman%2DFried%20sent%20his,Bankman%2DFried%20hit%20the%20shelves. I find this fascinating as it speaks to the personality of SBF. He talks about a lack of empathy (some self-awareness?) and putting all of his attention into his work.
Well, I am happy someone in the business of cryptocurrency is finally telling the truth. I doubt Mr. Wang is doing it out the goodness of his heart, I would bet he got a plea deal (I am not aware if he did), but regardless, moving forward with a conviction of the guilty will benefit the long term health of cryptocurrency.
