Because if he fixes it, he's admitting that there is a fundamental flaw in his vision that fora should be different from how they were for the first few decades of internetz. If forum posts are ephemeral, it probably doesn't matter that quote attribution (and with it the ability to follow the thread of a discussion easily) has been discarded. The archive of rec.bicycles.tech suggests that fora are not ephemeral, they have a long tail where strangers from the future can see how generous Sheldon and Jobst were in giving their time to educate people.
