It's telling how the SoftBank Vision Fund has been ridiculed way more for bad investments than its Silicon Valley funding targets (https://visionfund.com/portfolio - this includes at least one prominent YC company which received its investment 3 months after the Khashoggi murder, btw) have been criticized for accepting Saudi blood money.

Hard to put a price on reputation, but I suspect they have a harder time raising money for their Neom project

It rather smashed their attempt to economically open up Saudi Arabia to new forms of investment, at least for a decade. MBS had tried to set up a whirlwind effort to establish a 'new' Saudi Arabia and was spending a lot of money and effort to lure large investors to partner with. His 2018 tour of Silicon Valley, meeting with prominent tech players, wouldn't be possible post Khashoggi, those people stopped taking meetings with MBS afterward. Eventually the potentcy of that story will fade of course.
