We expect the primary benefits of this grant to stem from our partnership with OpenAI, rather than simply from contributing funding toward OpenAI’s work. While we would also expect general support for OpenAI to be likely beneficial on its own, the case for this grant hinges on the benefits we anticipate from our partnership, particularly the opportunity to help play a role in OpenAI’s approach to safety and governance issues.
So the case for the grant wasn't "we think it's good to make OAI go faster/better".
Why do you think the grant was bad? E.g. I don't think "OAI is bad" would suffice to establish that the grant was bad.
