tag 411953 + confirmed thanks Hi,
I emailed Richard Stallman (FSF) and Robert Chassell (the original author). Robert replied that he considered the Preface to be a secondary section because it described how he thought of his audience; but that he didn't really care; Richard replied that he Robert's reasons seemed sound, and that he didn't see any reason to take any action. So afaics this is a valid bug, and isn't going to be resolved upstream, so a move to non-free is definitely needed. Cheers, aj
