"[Autodesk] lost half its market value in one day".

I'd say Autodesk didn't lose its intrinsic value. In Walker's words:

How can I possibly impugn the performance of the management of Autodesk when Autodesk has just finished the most successful year in its entire history? We have highest sales, highest profit, largest number of new products, greatest market share, broadest international distribution, more employees, more technology in the lab, more products scheduled for introduction next year than ever, okay. That's not a record of failure. The fact that our earnings were lower in the fourth quarter than some people on Wall Street expected because we sell to the two most cyclical industries in the world, construction and building, and we're in the middle of a depression, is not anything that has to do with Autodesk strategy. We began this year with about a 70% market share in the CAD business, we ended the year with a 71% market share in the CAD business--71.4 I believe it is. That's not a company that's being clobbered by competition. That's not a Lotus being clobbered by itself. That's a company that needs to build on the base that we have, and expand that base with additional products, with additional platforms such as Windows, to broaden to the point that we are a broadly diversified company. That has been our goal since the foundation of the company. We have been in the multimedia market for several years; we're in the retail market--we're increasing all that focus as time goes on.

Also, could you give specific examples of what Walker said in the interview that could be considered a big mistake?

The reporter who interviewed Walker started with what could be classified as "incoherent babbling":

GZ: I'll just remind 'ya that this is a newspaper interview and that we'll just treat it as such. Ah, well listen, I appreciate the chance to come by and talk with y'all cause, let's see, Autodesk is a very interesting company and, uh, you know, for reasons that have to do with the fact that, uh, they're just so many things we can get to... we haven't--haven't really paid it a lot of, much attention in the couple of years I've been covering software--I also cover personal computers--but, uh, I've had a chance to do some--a little bit of boning up on the company and, you know, I'm real grateful that I had a chance to come by and talk because, uh, there's really, is no substitute for talking to senior management when it comes to assessing how a company is doing or what it's up to so, uh, I hope that... now I don't know what kind of time frame you had, but I hope we can get through a lot of things and, I, I hope also you'll appreciate that, uh, you know, a lot more about the company than I do and I will benefit by whatever time you can, you can share with me because, ah, naturally I have a lot of qu... you know... there's a lot of things I'm trying to come to grips with and... and in a lot of ways you're the best people to help me.

So, a scenario: imagine that a potential new employee showed up to interview at your company and you posed to him a somewhat open-ended question, and he responded by babbling. How would you feel about the candidate's credibility or competence? Not good, I'd imagine.

The reporter was unfortunately dumb, and it is very easy to make mistakes when dealing with dumb people. I specifically chose the phrase "deal with dumb people" because that is what what you have to do in the above scenario -- uninformed, ignorant people who have strong opinions are attempting to frame you in a particular light, and you have to deal with the results.

John appears to have thought quickly and dealt with this dumb person swiftly. So, picture yourself in his situation: "I have just invited this reporter to ask questions of myself and the upper management of my company. I just discovered that he is unprofessional, somewhat incomprehensible, and has ulterior motives that were not communicated. Therefore, I am being bullied." What do you do? How do you respond in that type of situation? Throw him out? Can't, that would look terrible. Excuse yourself but let him continue to interview upper management? Same thing. So John had to proceed by dealing with a bully, and he seemed to have done just that. He seemed to have handled it OK, at least to me.

Anyway, that's my thought process, and I'm quite interested to hear yours, if you get time.

EDIT: Here are a couple amusing gems in the interview transcript. "GZ" is the reporter.

JW: I thought we weren't here to discuss personalities. That's what you said.

GZ: Yeah, yeah, right. We're not going to discuss personalities. That's right. But the personalities... People run this company, right?

JW: People run every company.

...

GZ: Do you undermine senior management by distributing a paper like this?

JW: No.

GZ: You don't.

JW: All of the senior management who was in charge then are in charge now. We've reorganised a little bit, but...

GZ: Well, Al Green is outgoing, I mean, I mean one could say, ad hoc, that senior management was undermined, I mean in the sense that, that...

JW: You could say that. It's not true.

...

GZ: The, the sad fact is, is that if you look at the successful software companies and you look at the unsuccessful ones, uh, the Ashton-Tates and the Lotuses, they don't have that [technical] person there. The Borlands and the Microsofts, the Symantecs--they do.

JW: I disagree with you. The largest software company in the world is IBM. It isn't run by a software guy.

GZ: Would you be happy with their record? (Laughs condescendingly.) Would 'ya, would 'ya...

JW: Fifteen per cent compounded growth for a century? Yes, sir, I'd be happy with that record.

...

GZ: Okay, so, what, I mean, what, in terms of Alvar's replacement, then, what, what is your thinking about, about that? You need someone who will just fit in, with the strong team that 'ya have already?

JW: (Interrupting). I don't need. I'm not on the CEO search committee; that's a board matter. And the board, is the board, which is charged by the investors...

GZ: (Interrupting). You are on the board, no, right?

JW: No, I'm not on the board.

GZ: You're not on the board anymore.

JW: I haven't been since 1988.

GZ: All right. (Long pause.)

...

GZ: What was the reaction, of, of folks to the, to the letter?

JW: Ahhhh, I think it was, uh, a little like when you fire a shotgun in an aviary, there was silence at first...

GZ: (Interrupting). In a, in a, in an ``ave-ary''?

JW: In an aviary.

GZ: Aver-arary, okay.

JW: You know, where they have birds?

GZ: Um-hummm.

My conclusion: John Walker is a badass android, and this reporter has some serious thought disorder issues.
