I had to upvote and add to this comment to emphasize your point. I haven't looked through Google's SEC filings for what Larry's actual comments are, but he does need to remember that it's not "his" company anymore and he is partially a billionaire because Google went public (in exchange for getting public money and boosting the value of his own net worth, Google has been able to use that public funding for its continued growth). He likely would've been rich had Google not gone public, but it did and it'd be hard to argue against the positive boost it has given him.
He may not owe it to public investors to give bullshit earnings guidance, but he does owe it to them to answer their questions on how he intends on managing the company and transitively the investor's money.
