I think their problem is much worse than just being a question of improving data quality. They seem to get data from a lot of very different sources, and those simply do not fit together.

For example, in Stockholm Apple's map still shows most buildings as lying in the middle of some street. On the other hand, only relatively few businesses seem to be located in some kind of building. There seem to be quite obvious, and systematic, errors all over the place.
