I believe he is. However, I believe a lot of news organizations/blog owners are trying to do it these days. They will have very controversial/eye catching headlines with no substance in the article to gain more traction. Dvorak is a few steps ahead, he tries to justify those headlines by pulling fake data.
A frequent offender is Alley Insider and the entire Business Insider set of blogs. Henry Blodget's Internet Outsider blog used to be great, and SAI started nicely, but now it has devolved into a trolling + link-baiting mess. A search for 'killer site:businessinsider.com' shows how many titles they have that are -killer such as 'wikipedia-killer' 'google-killer' etc. They frequently take a poor claim or projection based on little to no evidence that is likely to be controversial, assume it is incontrovertible and publish a litany of bad arguments, stupid opinions and ridiculous forecasts.
The comments on these posts reflect the type of people to enjoy such a blog.
Peter Kafka used to blog for SAI and during his tenure there his posts were as bad as any other on that site and since he's moved to AllthingsD his posts have improved wholesale and are now informative, interesting and frequently make headlines on memetrackers such as Techmeme. I think it's some kind of policy, and I don't think it works given the greater exposure Kafka gets now than before when he was with SAI.
