In exactly the same way that I’d rather give to a direct-action effective charity than to an EA aggregator, I’d rather have end-result charities make the advertising/effect tradeoff than an upstream organization.
The kind of people who want to give to direct-action effective charities generally want to give to charities with low administrative overhead. As a result it makes sense to have other organisations focus more on the marketing.
