Yes. Rather than spending $1 on a project worth $10, the funder is spending $10 on the project — so the funder’s goals aren’t advanced. (Modulo that the retroactive-funding-recipients might donate their money in ways that advance the funder’s goals.)
Related, not sure: maybe it’s OK if the funder retroactively gives something like cost ÷ ex-ante-P(success). What eliminates the surplus is if the funder retroactively gives ex-post-value.
Edit: no, this mechanism doesn’t work. See this comment.
