I think they’re doing their best to help. From the resignation letter you linked (emphasis added):
We are devastated to say that it looks likely that there are many committed grants that the Future Fund will be unable to honor. We are so sorry that it has come to this. We are no longer employed by the Future Fund, but, in our personal capacities, we are exploring ways to help with this awful situation. We joined the Future Fund to support incredible people and projects, and this outcome is heartbreaking to us.

Thanks for pointing this out.
I did read the post but obviously missed this part. I apologize.
