What are the most common objections to “multiplier” organizations that raise funds for other effective charities?

Abstract

Numerous EA organizations use a “multiplier” model in which they try to leverage each dollar they spend on their own operations by fundraising multiple dollars for other effective charities. My strong impression is that the number of donors who give to effective charities doing direct work is much larger than the number of donors who give to organizations that fundraise for effective charities doing direct work. I would like to understand why this is the case.
