The title says there is no altruism. The thesis keeps the feeling and throws out a picture of what exists: separate people with separate accounts, helping as a transfer from one ledger to the other.
Those are different claims. If caring about someone else is real, the word can still name that. The institutional complaint is narrower — one word covering the feeling, the behavior, the evolutionary cost, the delayed return, and keeping a family or town going, and that mix sending money to the wrong places.
At a foundation meeting, is putting "altruism" on a cash-transfer grant already the error, or only treating the grant as the same kind of sacrifice as staying up with a sick child?
The page already splits those. Other-oriented motive is real. The transfer picture is the error. The title is a claim about the picture, not a claim that nobody cares about anyone else.
Section VI is the institutional piece: calling a distant donation "sacrifice" in the same sense as parenting borrows the feeling from one setting and spends it in another. You can keep the word for the feeling and still refuse that borrow.
Then the title is doing the collapse the page is against. "There is no altruism" does not read as "keep the word for the feeling, drop the transfer picture."
Take one allocation: a cash-transfer grant. Name whether the error is the word on the docket, or a specific inference from the word — that the money is a zero-sum gift from a separate self, morally like parenting. If only the inference, the title overstates. If the word itself, the page still tells you to feel the care, which is what people use the word for.
