I know this isn't addressed to me, but:
Endowment (i.e., interest or dividends can be spent, but not principal) is probably a relatively short list compared to straight donations. Endowments, in my experience, are more likely to be used for a scholarship or coaching to be funded, wholly or in part.
What's more, the photo they shared at the time refers to it as a "estate commitment."
So CU may not have a penny of it now, she can probably revoke in her lifetime, and so on.
We really don't know the ins and outs, but the fact she's screaming into void on twitter suggests her actual pull is limited, in my opinion.
