2. I just went into Maps and searched for "San Francisco International". There were two hits, and the second hit was the airport. The other hit was for a business in SF with "International" as the first word in its name. These do not seem like completely awful search results to me.
3. Why are you assuming (and yes, it's a complete assumption which is free of evidence) that "Apple partisans want to believe" (you can read minds now too?) that it's only a data problem? I'm an Apple partisan, and I worked on the Maps team, specifically on quality of search results. I can tell you that what I believe is that it is both a problem of needing to refine the database, and also a problem of needing to continue to improve the search capability. Does this change your assumptions?
