Yahoo's reputation is really going to take a hit over this one, and that's a huge shame for the developers that work there. From YQL to Yahoo Maps to YUI, there are obviously a really, really talented bunch of people in there somewhere. It might be time for them to find a new home.
No. But I would argue that Apple is a very different company. The Yahoo services I mentioned are very developer-centric, and their reputation amongst the developer community is important. I'll think twice about using Yahoo Maps now, for example. Apple doesn't really have anything like that. We use XCode because there are no alternatives.
