I’m not sure that doing something that only directly benefits other people but makes you feel better about yourself as you’ve done something good (or less bad as you’ve not spent the money on something you’d have felt guilty about) isn’t in your self-interest. Other kinds of making yourself feel good count.

Hence why they like to specify “rational” self interest.
