That said, I don't remember the previous posting of this article, so linking to previous comments is useful. It lets me compare the discussions and see how opinions do or don't change.
Whose comment? fjarlq's comment? If so, I also might be wrong, but I read it as "Here's old discussion on the topic. Might be worth reading to see if what you want to talk about today has already been hashed out, or if there's discussion that you might find interesting.".
I see where you're coming from, but I think everyone is well served not always looking for ulterior motives where there are none. A link to a rich previous discussion on a topic is almost always both relevant and informative, and saves others from having to go an search for the relevant thread(s).
If there's one great failing of computer science as a field, it is the lack of history -- people just don't know what was, or how things came to be. And so we have a lot of effort wasted on recreating yesterdays mistakes, today, rather than building on old solutions to create better ones for tomorrow (to partly paraphrase Alan Kay).
