Article he is referring to is in Developer Works, and is written by:
"Michael Abernethy, Freelance Programmer, Freelancer"
The only thing IBM related is the fact that IBM supports the DeveloperWorks community and pretty much lets anyone post anything there that sounds even remotely decent. It's up to the commenters and others to determine how useful the article is.
The OP clearly is new to DeveloperWorks. Does he also think Blogspot is responsible for all content published under Blogspot.com or tumblr responsible for all under tumblr.com?

I have also heard Charlie Robbins say you can't build a web framework without threads, in spite of Python having multiple single threaded systems. When challenged, he said, "that's still a thread." Riiiiight...
So, back at you nodejitsu.
There are plenty of positive node.js articles such as http://www.ibm.com/developerworks/cloud/library/cl-nodejsclo...
With that being said, the clout gained from being posted on IBM.com means a lot to many people who have no idea how Developer Works is run and randomly come across the article from a google search.
People who have a need in such a solution already know about it, and for the rest it's a niche product that solves a very specific problem for very specific products. Next.
