Edit January 19: FLI has made a substantive statement about this issue:
https://futureoflife.org/rejection_statement/
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.

I think this sort of reasoning is helpful and generally underutilized. But one thing to keep in mind is that organizations can take weirdly long times to make even super obvious public statements relative to the value of getting clarification public, mostly for silly internal reasons.
(Ex: not clear who needs to approve, someone who would normally look at it is traveling, someone misses that this is urgent, ...)
