Gruber hasn't written any book. John Battelle has written a book on Google.
Also, I think it's extremely disingenuous to conflate Gruber's income from his blog with the income Batelle derives from being the founder of Federated Media Publishers. To say that Battelle has an agenda in supporting Google's practice is obvious.
