> "We want to make sure you understand that if you don't sign, it could impact your equity," one rep told an outgoing employee, according to Vox.

The article is doing a lot of click-bait stuff here. The quote, without the source, is shown at the top of the article, near Sam Altman's face and a title referencing Sam Altman. However, the quote is not from Sam Altman, which makes its placement a bit disingenuous.

I am not invested in defending Altman, but this type of journalism is trash clickbait and a far bigger issue than a tech company threatening employees' vested equity unless they comply in some sort of non-NDA NDA scheme.
