Edit January 19: FLI has made a substantive statement about this issue:

This seems concerning. It is claimed that the Future of Life Institute, run by MIT professor Max Tegmark, offered but did not pay out a grant to a Swedish far-right foundation. The character of this foundation and its associates is well-known in Sweden. Expo is an old and respected watchdog organization specialized on neo-nazism and related movements.

(Sort of starting another thread here), based on my knowledge of how effective, reasonable boards function, I think there is a good chance there would be no governance you are describing for a number of reasons, and such governance when it occurs is usually performative. More subtly, this is not a defect, this is what should be done and how things are done in practice.
My guess is that this would have gone through (80%). In this case, having a strong singular founder and a billionaire donor increases the chances this goes through. Tegmark's other communications choices, add to my sense this (I don't have time to elaborate, they aren't severe, but suggest a low sense of discipline and a sense of personal esteem).
I could be wrong (contrary evidence that would change my mind would be past actions or an unusually strong board member).
