I have difficulty taking this seriously. Someone else can respond to it.

Transparency requires reevaluation if we are talking about a small group of people that are responsible to give the thing in control of the fate of the universe and all entities in it it's plan of action. That is, if you were able to evaluate that this is (1) necessary, (2) possible, (3) you are the right people for the job.

This lack of transparency could make people think (1) this is bullshit, (2) it's impossible to do anyway, (3) you might apply a CEV of the SIAI rather than humanity, (4) given 3' the utility payoff is higher donating to GiveWell's top ranked charities.
