The major paradigm shift between these two pauses in time was the shift to the internet. In 2001, when the book was written, the, "road warrior," was more common and relevant than in 2009, when the movie was made. The dotcom boom was in bloom, but not yet fully developed. To remain relevant, the writers of the film chose to use the internet as the threat, rather than a company transition. It's less nebulous, and easier to capture, as the internal monologue of the protagonist is difficult to transition to film.
