Secondly, Mr. Jobs has had cancer, for crying out loud  and in the public mind, a particularly insidious kind. Although several doctors I spoke to say that the kind of cancer he had, and the kind of operation he underwent, give him a better-than-even chance of living a long and happy life, there are no guarantees with cancer. We all know that. Which is all the more reason why, at a minimum, Apple should flatten the rumor that his cancer has recurred  even if it won’t go further than that. “Not being able to provide a statement effectively dismissing the question is really unsatisfactory to most investors,” said A. M. Sacconaghi Jr., who follows the company for Sanford C. Bernstein.

The final reason, to be blunt about it, is that Apple simply can’t be trusted to tell truth about its chief executive. Under Mr. Jobs, Apple has created a culture of secrecy that has served it well in many ways  the speculation over which products Apple will unveil at the annual MacWorld conference has been one of the company’s best marketing tools. But that same culture poisons its corporate governance. Apple tells analysts far less about its operations than most companies do. It turns low-level decisions into state secrets. Directors are often left out of the loop. And it dissembles with impunity.

As, indeed, it has in this latest episode. On Wednesday, John Markoff reported in The New York Times that Mr. Jobs had had a surgical procedure earlier this year, the details of which remain unclear. I hear that he has had ongoing digestive difficulties, which have contributed to his weight loss  possibly a side effect of the surgery. And in the weeks leading up to the conference, he came down with an infection, which had a lot to do with why he looked so gaunt. It wasn’t cancer, thank goodness. But was more than a “common bug.” By claiming Mr. Jobs had a bug, Apple wasn’t just going dark on its shareholders. It was deceiving them.

It would be horrible if Mr. Jobs had a recurrence of cancer. I hope it never happens. At 53, he is in the prime of his life, the father of a young family. And for the rest of us, it’s exhilarating watching him work his magic in the marketplace. Steve Jobs has created more value and driven more innovation than just about anybody in business. Who doesn’t want to see what he’ll come up with next?

He also, though, needs to treat his shareholders with at least a modicum of respect. And telling them whether or not he is sick would be a good place to start.

On Thursday afternoon, several hours after I’d gotten my final “Steve’s health is a private matter”  and much to my amazement  Mr. Jobs called me. “This is Steve Jobs,” he began. “You think I’m an arrogant [expletive] who thinks he’s above the law, and I think you’re a slime bucket who gets most of his facts wrong.” After that rather arresting opening, he went on to say that he would give me some details about his recent health problems, but only if I would agree to keep them off the record. I tried to argue him out of it, but he said he wouldn’t talk if I insisted on an on-the-record conversation. So I agreed.

Because the conversation was off the record, I cannot disclose what Mr. Jobs told me. Suffice it to say that I didn’t hear anything that contradicted the reporting that John Markoff and I did this week. While his health problems amounted to a good deal more than “a common bug,” they weren’t life-threatening and he doesn’t have a recurrence of cancer. After he hung up the phone, it occurred to me that I had just been handed, by Mr. Jobs himself, the very information he was refusing to share with the shareholders who have entrusted him with their money.

You would think he’d want them to know before me. But apparently not.
