I wonder though if any users actually care? Seems like it's entirely a business issue between two competitive sites. If I were to ask a question I would certainly welcome any and all answers and, personally, not care if I was credited for asking the original question. (especially if the responses were good and helpful)

Fights are most bitter when the stakes are low. Let's face it, the value supposedly comes from the quality of the answers rather than the questions...although from the site owners perspective, the questions are time candy which keeps the users hanging around the website.
