Google is losing its product development chief Jonathan Rosenberg, who reportedly felt he couldn't give the company's brand new retread CEO Larry Page the open-ended commitment to stay on the job that Page wanted. Or so the story goes.

Rosenberg was planning to leave in 2013 when his younger kid starts college. Now he's going this summer with plans to write a book with Google's old CEO-now-executive chairman Eric Schmidt about Google's management culture. Apparently he'll come back as a Google consultant after a vacation.

Of course, Page wants to focus on products and Rosenberg told the San Jose Mercury News - which broke the story - that Page needed to build his own executive team. Ken Aulette, who wrote the book "Googled: The End of the World as We Know It," told the paper that Page may be glad to see the back of Rosenberg. "Jonathan has sway over much of the management systems at Google. Did we come to exemplify the bureaucracy Larry Page condemns? I don't know, but I suspect the answer is yes."

Page released a statement saying, "We tried to hire Jonathan multiple times because he was the only person we could imagine doing the job. It's lucky we were so persistent because he's built an amazing team - hiring great people, who've created amazing products that have benefited over a billion users around the world."

Rosenberg, who served a stint at Apple, was an Excite@Home refugee when Google hired him nine years ago.
