The only people I see acting like children here are Apple fanboys, Google fanboys, and tech blog writers. Not Apple themselves, nor Google, except where one of the three groups above starts putting words in their mouth.

Full disclosure: I am one of those three types of people above but that doesn't mean I agree with the actions of others in that group.

Perhaps, but you really just have no idea what conversations are happening behind closed doors.

Google did something to cause Apple to do this, as well as Apple already reducing their use of Google, and it's all private. Childish things would include talking in public.

Probably Apple had preferential access to API ( like free for 5 years ), Apple still wanted to have free access plus probably extended APIs (like directions, vector maps). But since Google is not providing Maps API for free anymore for high volume, they may have wanted Apple to pay like everybody else. Apple said no (too expensive, akin to microsoft tax on FAT LFN ), Google said sorry. End of story.

How do you know Google did anything?

They took it public with this statement, right?
