Richard Yetter Chappell is a partisan of "Effective [sic] Altruism" (i.e., measurable short-term effects altruism), and I am not, but he certainly does a good number on what sounds like a very weak collection of criticisms; an amusing excerpt:

At the end of the first chapter (p. 7), we’re told that:

"[failing to fund] work being done by a Black activist in Black communities is upholding white supremacist ideas about which communities are worthy of support and which ones aren’t. In other words, it’s racist, plain and simple."

The second chapter tells us that featuring endorsements from attractive celebrities constitutes “body shaming, ableism, and sexism.” (p. 13)

From the third, we learn that “Normative Whiteness is cooked into the ideological foundation, because it focuses on maximizing the effectiveness of donors’ resources.” (p. 28)

And so on.

It’s like a caricature of delusional humanities professors invented to provide fodder to Tucker Carlson. Except it’s real. Apparently some people really think this kind of thing passes for argumentation.
