Apples strategy to surprise Google with early release certainly seems to have paid off with Google taking so long on releasing their own app. Many are going to get over the initial issues with Maps and stick with it.
This map fiasco has convinced me that Apple is on a downward spiral. You are right that Apple has shown it was only concerned with hurting Google and didn't care one bit what problems it created for its own users.
If Apple cared at all in the post-Jobs era about its user experience, it would at a minimum have kept its previous mapping app as an optional download. That would at least have provided an option to avoid a hugely degraded experience for its own users, and forced its own mapping team to have some competition. Instead, it showed that it cared only about its corporate strategies and caved to its product managers who didn't want competition. It has shown its users that it is willing to pull the rug out from under them at any time to do this, so anyone with a brain has been warned.
Frankly, the new Apple maps are worse then just bad, and have sold out to the worst of local advertising, such as the numerous Yelp links. I'm currently in London, and the Apple map doesn't even show Trafalgar Square, but instead shows hundreds of completely unreliable Yelp links to stores that are of no relevance. Every other major landmark is also missing (presumably not commercial enough yada), and that is just one of a million problems. Calling it a fail is too generous.
