The article in question was about using a commercial product. Not in itself bad, or unusal, however in order to use the code described one would have to purchase the product. As Chris has explained he has tried to limit articles to those that the ordinary development can use, without additional purchases. I believe the author was hit by copy cat voters, once one chimed in about inappropriate material, others echoed the feeling. I also believe the author, with a self professed long history of development took it a little too far with a sour grapes attitude and a "I'll take my toys and leave" approach.
