I don't know that we disagree very much, but I don’t want to lose sight of the original issue as to whether EY’s characterization accurately reflected what multifoliaterose was saying. I think we may agree that it takes an extra step in interpreting multifoliaterose’s post to get to EY’s characterization, and that there may be sufficient ambiguity in the original post such that not everyone would take that step:

Also, multi isn't denying that utilitymonster's money would be better spent in some third way that directly pertains to existential risk. (However, such a denial may be implicit in multi's own decision to give to GiveWell's charities, depending on why he does it.)

I did implicitly read such a denial into the original post. As Carl noted:

The invocation of VillageReach in addressing those aggregative utilitarians concerned about astronomical waste here seems baffling to me.

For me, the references to the Givewell-approved charities and the lack of references to alternate existential risk reducing charities like FHI seemed to suggest that multifoliaterose was implicitly denying the existence of a third alternative. Perhaps EY read the post similarly.
