Because UDE seems to have this policy where if they do answer a question, it will be the barest minimum amount of information they can possible give you. I think it stems from the idea that a lot of players also seem to have (at least with regard to forums), or it may be that UDE's tendency to be so spare in their answers has engendered this idea with players, in that most seem to think rulings should never be discussed beyond the initial answer to the initial question; the excuse being given that additional discussion will only lead to confusion.
You'll notice, that most YGO Rules forums are nothing but an endless archive of locked threads, with a question, an answer, and anything beyond that very rare, and frequently chastised by other members. In contrast, you may also notice that's not the case here, with some of our rules threads spanning the decade. I figure, and my predecessors figured, that if your going to tell people to use the search feature, that your archived information should at least be up to date. But, alas, I'm ranting. I do feel, however, that UDE has had a very influential role in engendering that attitude, particularly by the way they deal with rulings questions, whether by choice, or by direct instruction from Konami.
