Some EA-ish organisations are legally part of universities. For example, FHI is part of Oxford, and CHAI is part of UC Berkeley. In both cases when I donated to these organisations in the past it was legally a restricted donation to the university, to my recollection. I assume GPI is also part of Oxford.
(To be clear, I am not arguing that you should give to these two specific organisations).
