I guess we'll never know for sure if Steve Jobs egged on his buddy Larry Ellison to throw this sucker punch at Android but given his apoplectic reaction to Android it sure seems likely.
Power player A meets power player B, they discuss what they hope to do in the near future - plans and interests. Perhaps they will have matters of mutual interest - thats great.
Then they seperately take action, happy to know what positions and interests the other players in the game have.
Apple and Oracle were both threatened by Android. No-one needed egging on, no-one needed secret deals. They were open and above board about wanting to screw over Larry and Sergey. :-)
