Think before Android. Things were good between Apple and Google. Eric Schmidt was sitting on Apple's board of directors. Albeit a spy of sort but still he was there a long while.
It was not until Google released Android, changed how the original Android phone looked and and feel and the whole UI did Apple felt betrayed.
I know that there are a lot of "he said, she said" but the point is that Apple and Google were fine before the first Android release in late 2007, the G1 by T-Mobile.
If tomorrow, Google suddenly said they were relinquishing control of Android to a true open source community and publicly declared that it will not contribute any more resource to its development, it may just be enough, over time, for Apple and Google to become close again.
Apple was not interested in cloud computing much as it is now before the two tech giants parted ways. I doubt iCloud would be where it is today. The acceleration in which Apple worked on its cloud initiatives was largely brought on by Google's competition in the mobile hardware and software market.
So, Reuters is wrong. Apple is after Android. And it is seems like Apple is going after Google, that's just a coincidence. Consider this. If Apple wants to go after Google, I think it would be working on a search engine right about now.
