A CoC that against economic incentives is unlikely to work out.

Instead, they should work to change the incentives -- likely by paying more attention to them as an organization, talking about people who contribute them on the project's page and blog the same as they do for major technical work, and possibly even bringing on maintainers focused on (soft) docs.

Trading attention and prestige for content might work, shaming the people who produce content for not giving you the credit for free is unlikely to.

I don't think projects give soft docs the credit they deserve, so why are people so surprised that people develop that content elsewhere, where they're recognized for it?
