But the average person has been given the impression, however inadvertently, that the average "hacker" is engaging in clandestine, nefarious activities on the Internet. When I was in University I lost count of the number of people who freaked out because they saw me using a terminal and vim from my laptop during class.
This article refers to attackers, not hackers. The work "hack" does not occur once in the article. Calling these people attackers is accurate, and doesn't do anything to contribute to the people you describe thinking of you as a criminal, unless you think rerouting traffic in this way is in some way legitimate.
That isn't the complaint about this particular article. The complaint about this article is the botched reporting on what happened, and what MITM attacks are. This criticism was defended by pointing out that misinformation from the media has the potential to have a negative effect. An example given of this was the careless use of the word "hacker" by the media "in general".
jlgreco is correct regarding my meaning and intentions. I have a problem with the lack of accuracy in technical reporting because it's usually sensational (and I'm sure this is true in other disciplines as well).
