I accept the correction.

ADDED. Well, if I wanted to get technical, I would point out that the post is near the lower limit in size of works that can be copyrighted. That is, even in the best of circumstances, it would be difficult to prevail in a copyright infringement suit on the basis of such a small number of words, and the particular part of copyright law that deals with movies based on novels is probably far from the best of circumstances. So, I could make the technical argument that my statement was probably correct because I was referring to one particular rather-short Less-Wrong post, not copyrightable works in general including things like novels. But enough!
