I remember hearing that people used it as a way to signal that they were too busy, too on the go, too important to use proper punctuation..it was an obnoxious c suite trend as long as I can remember. Like you're always trying to signal that you were doing all of your comms from your cell phone between meetings/travelling. Given this article's tone and content I would say that what the author is trying to emulate or convey , maybe subconciously.
