I’m sure they could have found someone in the EA ecoystem to throw them money if it weren’t for the fundraising freeze. This seems like a case of Oxford killing the institute deliberately. The 2020 freeze predates the Bostrom email, this guy who was consulted by oxford said there was a dysfunctional relationship for many years.
It’s not like oxford is hurting for money, they probably just decided FHI was too much of a pain to work with and hurt the oxford brand.
