It's not just Ars Technica. I would go as far as saying the big majority. I work at the biggest alliance of public service media in EU, and my role required me to interact with editors. I often do not like painting with broad brush, but I am yet to meet a humble editor yet. They approach everything with a "I know better than anyone else" attitude. Probably the "public" aspect of the media, but I woupd argue it's editorial aspect too. The rest of the staff are often very nice and down to earth.

<< They approach everything with a "I know better than anyone else" attitude.

My charitable read is that if one has to interact with the public, one naturally develops an understanding of what is wrong with it.
