I agree that Janes' subscribers are using their corporate credit cards to pay the subscription costs, but I also think that Gigaom had the potentials to walk into the same path.
Take a look at the first screenshot in the story[1], Om Malik describes the site in 2006 as a "broadband weblog". The kind of quality articles on Gigaom were not comparable with link-baity nature of TechCrunch/Mashable or Engadget/Gizmodo. They could have been the Janes of IT industry if they wanted to. Or at least be as affordable as the AviationWeek.
Notice someone on this thread is describing Gigaom as "boring", I take that as a compliment about the fact that the site was very industry-centric and devoid of click-baity stories.
