I think it perhaps was unfortunate that this article was published in its current form (and to be honest given the negative reaction I'm suprised it hasn't been updated or removed). The technical aspects that are discussed are actually quite interesting and worth presenting, its just a shame they seem be intervowen around a personal attack. And with comments like "Oh how we laughed" and "I'm sure that would be no problem for a technocrat like you now, would it Axel?", I don't think the editors can really deny this.
Sarcasm can be amusing, but when it is used on a personal level and in a popular public forum I don't think it is really excusable or responsible. My gut feeling is that perhaps Drobe should review their policy with regards to articles and comments, this certainly isn't the first time this sort of thing has happened. Personally I would prefer articles to be less opinionated.
Finally, someone previously mentioned libel action. It is worth noting that the libel laws for publishing on the internet (in the UK anyway) are currently being reviewed with the intention to make them much more stringent.
