Umm.. The author is not objective. He (Norman Matloff) had long since been spouting off on H1-B and why its bad. He also found a way to work it in to the article, in the same way that he had used in the past so effectively, to scare the current programmer segment in to being worried for their jobs.
I am not saying that H1-B isnt abused, but his take on it is largely one sided, and against.
