Meta leadership perhaps 'didn't know how bad the harm was' - former employee

The lawyer then asks Meta whistleblower Arturo Béjar about attempts he made to raise safety issues as he saw them. He shows the jury a chain of emails from Béjar to Chris Cox, who Bejar describes as "Mark Zuckerberg's right hand man".

"I was trying to communicate... how big the gap was between what users were telling the company was harm that they were experiencing versus what the company was prioritising on and communicating to the public about harm."

Again Béjar, tells the court that prevalence of policy-violating content is not the same thing as someone experiencing harm, and is a "very narrow measure of a very specific thing".

Béjar says whenever Mark Zuckerberg was asked about harm internally, he would immediately start talking about prevalence, which made him think this was how Zuckerberg thought about the concept.

"His [Cox's] response to this was very kind and then laying out the groundwork for eventually bringing it up to Mark and the belief that they didn't know how bad the harm was and that was the reason that the company was acting the way it did."
