I disagree. While it //is// unprofessional to joke around with licensing, I think the author of the article (and some of the commenters her) seriously exaggerate the thread of a legal suit. Who will sue? EFF? Crockford? I am no expert in "license law", but I am sure a you-are-using-this-for-evil accusations would not stand a chance.
Corporations troll each other in court quite often, in order to bleed the defendant and/or force them to resolve the case off-court, for a sum of money. Using code licensed under such a troll-bait like the "good, not evil" clause while having nice corporate revenue is a big mistake.
