The article says that it was a phone survey. This means:
1: The people are obviously not "Luddites who mourned the demise of the telegraph and have also never used a telephone", since they used a phone to answer the survey questions.
2: Most of the tech-savvy people I know don't even have land lines. They use cell phones or things like Skype, which are difficult to survey for various reasons. The people who go those routes have generally used email. Therefore, the sample population was already skewed toward people who wouldn't have used email anyway.
