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.

It seems like the paper's dispute with their bank has been going on for a while before the recent drama, perhaps long enough to make the timelines match up. But yes, it's confusing to me why they couldn't just switch to another bank. Definitely possible that they are basically just out of money and their bank is trying to cut them off, but the paper is hyping this up as political persecution in order to buy time / gain some negotiating advantage. (Of course, regardless of what the actual story turns out to be, there is seemingly zero reason for FLI money to be involved in this BS .)
